I am finally started to understand what really goes inside the head of those who do mass shooting or kill someone despite knowing the consequences. Many of them has a pressure valve which just stays tight but one day it just happens that their ego clashes with them and make them believe that they will only have inner satisfaction by doing "that". It's a battle against ego whole life. When ego wins, the chud goes berserk. Now, i dont necessarily think, It is just for "incels", it can be applied to any scenario, someone ignoring something for years but one day he cant and just "does the needful". i forgot which movie it was, it was about some office worker who gets stuck in traffic and start going on a killing spree until he is shot dead by a cop and whole movie is just about how ego won over him.
