Ah yes, the reasonable response in your scenario, is to attack a psychopath until they fucking kill you.

Who talked about reasonableness? If someone doesn't judge school shooters, there's clearly something wrong with him. If he then says that he was bullied, then maybe he wasn't as innocent as he's letting on.

What is this, contrarianism, or are you really fucking dumb enough to trot out "you were bullied and treated like shit because people realized you would kill them for bullying you"?

Why not both? Yes, I hold the highly contrarian position that it's bad to judge 'bullies' but not school shooters. Shocking, I know.

Because only a fucking troll or retard would sit there and tell me that "I realized poking a tiger would result in me being mauled, so I poked it until it ripped my guts out, because how dare it have the audacity to react to being antagonized".

If you're equating people with wild animals, then you could try to justify not 'judging' school shooters like the OP - but calling people wild animals is judgment in itself.
