Self-righteousness isn't necessarily pride or moral superiority. Rather, it's the belief that the focus of your own life is on yourself. Someone could be extremely humble, yet still fall to something as common as lying, in the interest of self preservation or comfort. Or, they steal something in the interest of having more for themselves. The fact that you only attack my use of the term "self-righteousness" is a straw man and not particularly important to the argument as a whole.

Easy. I manage my time and help them with whatever I have left after fulfilling my own [i]responsibilities.[/i] If I can finish my project tomorrow with plenty of time to spare, I help them as much as I can in the meantime. If I'm struggling to finish it myself, I refuse. The idea isn't that you can't do [i]anything[/i] for yourself, but rather that making your life about self-interest is the source of evil. The main problem with the scenario that you presented is that it assumes that one [i]action[/i] is inherently superior to another. Rather, it is only the [i]intention[/i] of humans that can be good or evil. There's a reason killing isn't evil in and of itself—people kill all the time in war or self defense. Instead, it is killing out of evil intentions that makes it murder instead of the act itself.
