When a man knowingly kills others, he is pure evil. He knew what he was doing. There is no valid excuse for killing another person except self-defense. He was most definitely pure evil.

I believe the correct word you should have used is "murder". There is no valid excuse for murder.

In times of war and the protection of innocents are quite valid excuses to kill.

Yeah it was evil but why is the question. I believe people like Rodgers, Adam Lamza, among others are differently wired from the get go and have problems dealing with society(like an alien dropped out of the skies)

Not able to separate reality from fantasy and the simple fact people, in general don't always do things logically, he existed in his own bubble of reality

Add in the influences of porno, violet games, sense of entitlement, etc and one creates an sociopath.

just my opinion.
