i hear this alot, especially from USamericans. it seems to make them feel better.
it would be far more accurate to say that humans have been tricked into killing each other by the 20% of society that is psychopathic.
but why do they have to be tricked? because they have human values - basic shit like "dont kill innocents" and "more freedom is a good thing" and "cruelty is wrong."
most people, while imperfect, practice human values most of the time. when they don't, they still aspire to, in general.
and some people are hell bent on living beneath human values.
like members of the democratic party of the USA, and the people who vote for them.
I'm barely defending murder or anything like it. I fail to see how others were simply tricked while Democrats and their supporters are somehow more conscious of their actions than others. I wouldn't give them that much credit.
