I don't look at Paragon/Renegade choices as good or evil, but rather as gracious/harsh. I didn't like the moral system in Mass Effect either way, hopefully they fixed it in ME2. I think that Deus Ex to this day isn't beaten in this regard, when there are no good/evil points, but characters simply reacting differently depending on your actions.Not me. It is so hard for me to play bad that I used the conversation trick to get Renegade achievement but I did get the different endings, if obonicus' spoiler is accurate that is kinda irritating for me I would have preferred the reverse leadership choice.
Though I have to admit that renegade Shepard was just really cool:
