Truth is per definition absolute, what we know of it less so.

Anyway, my wives don't let me sit on my arse debating metaphysics on an RPG forum all the time, especially when you people keep moving goal posts. But let me have one final say for now.
I'm not saying atheist cannot be moral or that the faithful never do harm, rather that atheist have no standard against which to measure goodness. You just don't seem to get that without Allah there can be no good or bad to begin with, only being. Your concept of what is good or bad is probably just Christian leftovers that have started to rot.
