That makes sense to me. So would you tend to try to avoid a situation where surrender is an option?The short answer to this question is that I would expect the players to handle the situation within the context of their characters, whatever that looks like. If the players are doing their jobs what happens next will flow naturally, whatever that thing is. What I don't do is go out of my way to insert this sort of situation into a game, nor try to manage what the characters' response might be outside of what the players decide to do within the confines of the established fiction. I have no interest in examining larger moral issues as a specific part of my gaming experience, although I'll freely admit that it does come up with some regularity regardless.
This isn’t a trap, I swear. I’m just curious, since this is an RPG issue (lethality and NPC morale) that fascinates me, and I often wonder how different people handle it.
