Humanity has justified an awful lot of shitty behavior on account of religion

That’s exactly my point?

If you take an in depth look of those events, there were always inherent political and economical motives. Explicitly saying that you want to assert authority, consolidate power, and acquire more land and wealth by slaughtering bunch of innocent people sounds awful, doesn’t it?

Saying that most wars are caused by religion seems like a stretch, considering conflicts have existed long before human even existed and fights are going to happen anyway. I’m not sure if that’s any worse than invading Iraq for “freedom” or Stalin and Mao killing their people because they were “counter-revolutionaries”
