Except that being a good guy doesn't mean you're capable of contending with or fighting against a Daedric prince.
What are you smoking? Good guys in what stories?
If youre a good guy, and someone is trying to kill you - you kill them first. That's what good guys do. Hell, you couldn't have made it to Markarth in the first place without killing anyone who was trying to kill you.
What am I smoking? I just mean "usually in stories" in the "trope" or archetypal sense. Good guys aren't ultra sensitive idealists - that's almost "too good". They usually fair minded, but do what they have to do. I'm agreeing with you = they kill if they're attacked. Generally speaking, in most stories. I don't know what your disagreement is with me.
Some even cause harm for a greater good. Think of umm.. John MacClane in Die Hard, for example (sorry, bear with me for a second). There's that moment where he sees the cop ignoring the building and driving away, and if he doesn't get his attention, the whole situation is worse. So he shoots at him and drops a body on his car. He causes the cop to crash. An ultra sensitive guy might've hestitated, but a good character does what they have to do sometimes.
