Did you look up what naturally aggressive means? Bullying is evil...people have killed themselves over bullying so I don't get your comparison.
Ock responded the way anyone would with his life situations. He wasn't naturally aggressive or evil before the accident or he would have walked around punching people for looking at him. Anyone who responds with aggression in every situation either has a problem or they are evil. Ock had weapons before his accident that he didn't use.
Do you disagree that the accident is what made him evil? Do you really think Ock was a bad person before his accident? Just answer those two questions.
"You can leave a penny, you can't take a penny. You can leave a penny anytime. You have to spend $10 to take a penny. Store policy."
"Since when has this been store policy?"
"Uh, since my boss made up the policy. You gonna pay? You're holding up my line of one other person. You can't afford your milk, step aside. What, daddy didn't give you enough milk money? Little baby gonna cry about it? Just step aside."
And that is how Uncle Ben dies.
