When it is a case where a young buck goes on a shooting rampage, I will also bring into it the possibility of the black pill theory.
Get rejected by women enough and can't get laid so frustration leads to not having a purpose in life.
No one sees it coming. Only 19. WTF right? When we were 19, we never thought about doing these types of hideous crimes.
I do see myself doing stupid things but gladly that I got away with it. It is part of growing up like getting into trouble types of a thing but it has a better ending. We do things but we do not see the consequences. I get it, it is a part of growing up but still, shooting people or going on a suicide mission is not mentally normal.
Then again, I did not grow up playing COD or them shooting games either. I'm not laying the blames on video games either. I do not have enough information or studies to conclude this. I do know that my elders would scold us if we buy fake guns and what not. Now it all makes sense. They taught me young with a fishing pole in my hand thus why I fish. If they put a fake gun to my hand and expose me to it at an earlier age, I'll be a gun collector right now. Maybe, I dunno.
