It's lovely that we share a similar subjective view of some things. That in no way indicates an objective view exists. In fact I would suggest that I find nothing evil about some things that you consider evil.Thats good,rejecting evil is your first step towards faith.
So even if the one who threw the bomb over the head of innocents in Hiroshima was a religious one,but that won't let him escape by the severe punishment of god.
i do appreciate your example of how awful the evil work of people killing the others and
thats is the reason that god prepare a severe punishment for such ugly souls.
