My capacity for empathy has nothing to do with anything.

Again: I just happen to value human well-being, and as literally everybody in the universe, I will seek to act in accordance to my values, which usually easily puts me in the same camp as other people who value human well-being.

There are people out there who value “the word of the lord” or something like that more. Like they would prefer to kill wrong-believers because they value their religious text more than human life. They think they are “good” too. I don’t agree with them, but if MOST people did, then they would get to decide what “good” is.
