15 Marvel Superheroes That Have Committed Unspeakable Acts

Being a superhero is a huge responsibility and more often than not, our favourite Marvel superheroes come face to face with extremely difficult decisions. Having to sacrifice your loved ones for the greater good might not seem like the easiest decision to make, but when you're a superhero, your main goal is to save the world— at all costs.

Superheroes might start off strong and clean, but it is only a matter of time before they start to accumulate some skeletons in their closets, and this is because it is impossible to save everyone without sacrificing a few. To make matters worse, superheroes are often targeted by supervillains who want to ruin their lives or rule the world. These villains are merciless and often plot the gruesome deaths of their foe's lovers and friends— or the destruction of the world altogether.

In some cases, superheroes are the ones that go mad with power, vengeance, and anger, and commit unspeakable acts. But can we really blame them? These heroes are constantly pushed around, used, brainwashed, captured and manipulated by evil entities who wish them harm. With that said, is it really surprising that these superheroes crack every once in a while and end up killing innocent people?

Most people think that becoming a superhero would be the coolest thing in the word, but not everyone would agree. Sure, you would possess an amazing set of skills and powers, but you would always be bound by justice, vengeance, grief and denial. Thinking of all the lives you've saved might help you cope with your pain, however, it wouldn't erase the death toll you kept locked up in your brain.

via Comicbook

Before the Scarlet Witch went completely nuts and started killing some of her own fellow Avengers, her powers were increased by a form of energy called Chaos Magic. The Scarlet Witch's new and improved powers proved to be uncontrollable, causing her a great amount of mental strain. After suffering from a mental breakdown, the Scarlet Witch began to lash out, killing Agatha Harkness and a few other teammates.

To make matters worse, the psychotic Scarlet Witch used her powers on Jack of Hearts, making him float in front of the Avengers Mansion in a catatonic state. When Scott Lang saw the Jack of Hearts floating in front of his home, he immediately went outside to see what was happening. Unfortunately for him, this is exactly what the Scarlet Witch was banking on, and the second Lang was close enough to Jack, she blew him up. Lang was instantly blown to smithereens and wiped off the face of the Earth.

via Marvel Database - Wikia

Having to choose between killing your wife and saving humanity isn't really much of a choice. But in the end, most people would accept the fact that they had to kill the one they love for the greater good. When it comes to Namor's love life, this is pretty much what happened. Namor married an aquatic alien named Marrina, who had served with Alpha Flight for a number of years before falling for Namor. When Marrina and Namor were married, they began working with the Avengers and forming a strong alliance. However, all this changed when Marrina became pregnant with Namor's child.

Since Marrina had alien DNA, her genes began to mutate from the pregnancy, turning her into a giant evil sea creature. The Avengers managed to turn her back into her alien form for a brief goodbye, but her genes quickly mutated once more. Thor and Captain Marvel attempted to kill the vicious beast, but were unsuccessful. Ironically, the only person who could kill the sea creature was Namor, and so, he used an ebony blade to kill his wife and unborn child.

13 Phoenix Destroys A Planet

via Marvel Heroes Forums

We can argue that Jean Grey really isn't responsible for the Phoenix's actions, but in the end, they are one and the same. Sure, Grey might not like what her counterpart is doing, but she still hasn't done anything to stop herself from committing heinous crimes. The Phoenix might be hard to control, but it is still Grey's responsibility to stop her inner beasts from taking control of her very own body and killing the ones she loves the most.

Have you ever wondered why the Shi'ar tried to track Jean Grey down and kill her? If you have, you might have thought it was because the Shi'ar were madmen, but in reality they were simply seeking justice for the crimes committed by the Phoenix. What crimes you might ask? The crime of traveling to different corners of the Universe and releasing her full Phoenix potential on an entire solar system, destroying an entire planet in the process.

Bruce Banner was born into a chaotic household fuelled by an angry, alcoholic father. His father, Dr. Brian Banner, was an atomic physicist who was convinced that his work in radiation had affected his son's DNA, causing him to be born a mutant. Brian's wife, Rebecca, loved their son with all her heart, which eventually caused the couple to drift apart. One night, Brian murdered his wife in a fit of rage, landing himself in the loony-bin for 15 years.

Young Bruce was then raised by his aunt, Susan, who showed him nothing but love and compassion. He went on to pursue a career in nuclear science, showing clear signs of genius. While on the job, Bruce was exposed to massive amounts of radiation after a gamma bomb detonated. His DNA was once again altered, transforming him into the Hulk.

When Bruce's father was pardoned for his crime and released from the psychiatric hospital, he set out to find his son with the hopes of a happy reunion. Sadly, both men were ignited by anger once face-to-face, causing them to throw punches at each other in a graveyard. Brian was thrown back by his son's fist, cracking his head open on a tombstone and dying instantly. Although many people believed this to be an accident. Bruce later confirmed that he could have stopped himself, but didn't.

11 Wolverine Murdered His Children

There is nothing worse than losing a child, but in Wolverine's case, there might be a few things worse. Love has never been an easy topic for Wolverine, and this is simply because every single person he has ever loved has perished in the most gruesome way. Wolverine might not be responsible for many of their deaths, but when you think about it, his loved ones would still be alive if they'd never met him. In Wolverine Vol. 4, Logan's soul was sent to Hell as his body remained on Earth, possessed by demons. Wolverine eventually clawed himself back into his body, but he could not undo the massacres the demons had committed.

In order to seek revenge, Wolverine investigated his body-swap, and tracked down the people responsible for it. When Wolverine finally found the culprits, he was shocked to see that they were a group of people who had been wronged by him in the past and seeking revenge of their own. Wolverine brutally fought his way into the group's headquarters, viciously murdering a large number of mutant body guards to get to them. By the time he reached his foes, they had committed suicide to escape his clutches. However, they did leave a video behind explaining how the body guards he had killed, had actually been his own bastard children.

10 Thor Killed Wasp

Thor might be your all around good-guy, but that didn't stop him from taking the life of one of his dearest friends. In all fairness, Thor was put into a situation where he really had no choice in the matter. Having to kill his fellow Avenger to stop the world from blowing up isn't a choice he wanted to make, but it was kill or be killed. Nonetheless, he is still responsible for the death of Wasp, a death that he swore he would avenge.

When the Skrull Invasion was in full bloom, the Avengers sought to find a Skrull spaceship located in the Savage Land. When the heroes battled their foes, they were shocked to find them dressed in renditions of their own costumes. The Avengers were dismayed to learn that the Skrulls had been impersonating them for quite some time. Wasp was especially disgruntled because she learned that she had been given a growth serum by a Hank Pym imposter that would turn her into an explosive bio-weapon. When Wasp began to detonate, Thor had no choice but to use his hammer to turn the energy she was giving off back into herself, causing her to explode and die.

After marrying his longtime girlfriend, the Invisible Woman, Mister Fantastic was shocked to find out that he and his wife were having trouble conceiving. Instead of taking this as a sign, the couple went to extreme lengths to conceive and ended up getting pregnant. Sadly, after conceiving their son, Franklin, the Invisible Woman's blood cells began to carry a rare form of energy that threatened her life as well as that of her unborn child. To stop his wife and child from dying, Mister Fantastic, the Human Torch and the Thing entered a dimension called the Negative Zone, and extracted energy from the Rod. This energy regulated the Invisible Woman's blood cells and helped her give birth to a healthy baby boy.

All was well until Franklin turned 2 years old and started to demonstrate extremely powerful psionic powers. Unlike most mutant children, Franklin's powers began to manifest themselves very early on, turning him into an uncontrollable weapon. A villain named Annihilus captured Franklin, trapping him in a machine that released his full psionic potential. Franklin's powers were so strong that they threatened the world's existence. To stop his son from destroying Earth, Mister Fantastic used a device on his son, rendering him completely comatose.

It's no secret that Tony Stark is a piece of work who doesn't know when to bite his tongue. Yet somehow, we have managed to love him despite his egotistical personality. The superhero has proven time and time again that he only has his own best interest at heart and doesn't really care about anything besides his company, but that hasn't stopped his fans from praising him for his smarts and ingenuity.

During an AXIS crossover event, Iron Man's bad side found a way to maintain his evil persona once the crossover was reversed, making him the only hero to remain evil after the switch had occurred. Since everyone had turned back to normal, no one suspected that Iron Man had actually been overtaken by an evil force— except for Daredevil. When Daredevil found out that Iron Man was behind San Francisco's Extremis addiction, he tried to confront him. Sadly, Iron Man beat the crap out of Daredevil, gave him brain damage and made him forget all about the incident.

Kevin Ford might have committed worse crimes than killing his own father, but those crimes were committed when he had fully come to terms with his dark side. Before Ford traded in his name for Wither, turned dark and became a supervillain, he attended the Xavier Institute as a normal teenage mutant, made friends, and was considered one of the good guys.

Since a mutant's powers usually start to manifest themselves in their teenage years, Ford had absolutely no idea that he possessed the power of organic decay. One day, a young Ford started to notice that he could make plants decay at an alarming speed, but after a while, he realized that he could do much more than that. Unable to control his powers, Ford began to panic as his clothing started to decay directly off of his body. When his father tried to calm him down, Ford tried to shrug him off but ended up killing him by accident.

In The Incredible Hulk #279, the Hulk decided to crash his own party— literally. It had been a while since the Hulk had killed an innocent person by accident, and they wanted him to know that his efforts had not gone unnoticed. The Avengers built a 10-ton adamantium statue of the Hulk, erecting it in Central Park for everyone to see. To show Bruce how proud of him they were, the Avengers thought it would be a good idea to throw him a small party and present the statue to him. Sadly, this proved to be one of the most idiotic ideas they ever had.

The Avenger's actions seemed to piss Banner right off, and before they knew it, the green monster had switched places with him. The Hulk then ripped the statue from the ground and started beating Thor with it. After crushing Thor, the Hulk escaped in New York City, causing billions of dollars worth of damage.
