I always go with non-lethal if I'm given a choice. It doesn't really depend on the situation.
If I'm given the option to spare them, and stop them form doing what they do, then I will. I don't want to end "real" lives or digital ones and I feel bad when I have to(or I pretend it didn't happen). If I'm going to escape to a more fun or better world, then I want to be able to say that killing people is not more fun or better! So more or less difficult, stealth or not, directly or indirectly, I choose not to kill. You can't just be Texas and give everyone the death penalty.
My cousin usually takes the the "knock them out and then kill them" route. It might be funny but its still horrible and I will convert him to the ways of "not evil".
