I think the thrust of the OP is that the idea is for none of that to matter, and for people to debate the pros and cons of differing alignments.

Personally, I lean towards a kind of secular evil. Not through any malice towards other people, mind you, but because discarding the outdated mysticism that has become normal morality opens up so many options for gain.

I've made characters based on this notion, that have gotten ahead of others by being more ruthless or apparently unscrupulous, finding profit in any situation where others would have clung to their morality and, as a result, lost.
