Genocide here should be read as eradicating the beach head of an invading horde of enemies down to the last member.In any game where [morally good] = [engage in genocide/ torture] you can count me out.
As for torture, you might refer to the Chaotic Good. This would be a last resort to get the information needed (Where is the bomb? Where did you imprisoned the young girl? Quick before she dies or you will die too. That kind of stuff.)
