This guy does nothing but beat up other heroes in the comics and people love him. He's not an anti-hero like Wolverine, he has just a straight up villain attitude. So how is he classified as a superhero? I am not understanding.
He lives in the present moment without thought and takes action as neede3d in the moment just like animals that have no past or future thought. Past and future thought bring with it anger, hatred, revenge. No thought is purity of action in the moment without fault. That make him a hero.
Clearly you don't know the Hulk. He can think. He can and does help people. He was one of the original Avengers. He eventually had his own family. Yep, he's a hero.
the real problem with the hulk is that everyone keeps provoking him to make him angrier. firing machine guns and missiles isn't going to help the situation. the only way to stop the hulk is to calm him down.
