When a person or a nation practices power, it corrupts. A person feels, 'I have sacrificed, I have been wronged, and deserve to do what I want because I can do no wrong - I am always right - until they become assholes aka fascists.

My own country is being threatened by fascist fantasies. That does not mean that shooting fascists is what there is to be done.

The Hamas-Israel conflict has gone way beyond our stage and are both assholes who believe they are right to kill.
'Who was wronged most' games are played in narratives by both sides.
The real answer is that both are wrong.
