I heard a phrase today that I really agreed with.
"Evil only exists where we wish it to be."
At first glance one might think: "NO, why would anybody want evil to exist? it just does!"
But if we don't have evil, then we cant be good or righteous, and everybody want's to justify what they do.
So if we say "Those people are evil, we did this because _____," We are putting that evil else place so we can claim the high ground. And other people will do the same to us. It only exists where we want it.
Whoa, got a little existential there.
