I agree that religions seem to thrive on obliteration of self. The idea of what is right and wrong is based on God, Allah or the Big Green Rock on the Hill Behind the Village.
It would seem that in purely secular ethics, the individual is the vital and validating element of right and wrong. The ethic grows out of and is intrinsic to the individual, making it more difficult to justify harm to another person. With any degree of honestly and integrity, very difficult.
Religions based on some force outside the individual don't suffer from the same constraint as right and wrong exist independently of the individual.
I think you misheard. I'm sure God said "Doritos". Ranch flavored.
