So what's so bad about The Punisher?
On principle, people refuse to support murdering.
Why? What's wrong with murdering, say, Hitler met using a time machine?
The way I see it, the world is divided into two types of people:
Ethical/moral and psychopaths.
The first group follows the rules. The second breaks every rule they can get away with.
And so you end up with a situation where leg breakers and mobsters are living in your town hurting people, while common citizens who hate them yet don't support violence won't get involved.
What's so good about that? The psychopaths do whatever they want and no one will stand up to them, and this is a GOOD thing?
