Punisher
This one has two very simple reasons
The movies: God awful acting, god awful writing, god awful action. Never, ever, EVER make another 'The Punisher' movie again.
But the biggest reason is: he's a fucking idiot. He's not solving the crime problem, he's only making it worse. Let me ask you a question. If some random guy killed a member of your family, you'd want revenge, right? Doesn't matter what they did, they're still your family. So if it takes a criminal path to get to him, you would do it, wouldn't you.
Add in the fact he's MUDDERING people without due process, he's not a hero, he's not even an anti hero. He's a FUCKING terrorist. Yes, your wife being killed is sad, and the fact that the killer got off is horrible. BUT THAT'S WHEN YOU DON'T RESORT TO VIOLENCE. You fight to change the system, politically. But he doesn't want to do that. He doesn't want to do that because that's too hard, and he wants the easy solution to make himself feel better. Well, civil rights and women's rights were hard, but those got passed, didn't they?
