Fair enough. I did not mean he literally became a monster. His damaged brain caused him to lose control for a finite amount of time. He clearly realized he did something wrong afterwards based on the actions he took afterwards. True psychopaths would not behave in that way.He was not a monster. Monsters do not exist.
Humans do exist however and have proven throughout history they are capable of doing "monstrous" things.
If someone does something so bad that the other person cannot comprehend why they did it then they must be a monster, whether literally or figure of speech, rather than just accept that humans are complex.
Just my take.
It is not convenient. It is a conclusion based on scientists and doctors who study this stuff. It is not magic being pulled out of the air. Just saying he is a killer and saying end of story helps no one in the future. Studying causes helps future people. It amazes me I have to actually argue this point.I can't say what fucking caused him to murder his family. I'm not him I didn't know him so I can't even begin to know what his motivations were. I am not however, going to latch onto a convenient explanation that conceivably could be used as a means of justifying his actions. He's a piece of shit who in cold blood murdered his family. End of fucking story.
