How do you feel about characters that spare/only use non-lethal attacks on enemies that show clear intent to kill them?
Do you think this helps keep the show's atmosphere lighter and more enjoyable or is it something that detracts from the show but is more suitable for younger audiences?
the non-killing of enemy combatants is what marks them as being "good guys." If they started wiping out anyone that raised a hand to them they would be labeled "edgy and grimdark"
Personally I prefer it when the good guys kill the bad guys. It's just silly that this guy's trying to kill you and yet you're still pulling your punches. There's nothing wrong with killing someone who's trying to kill you. Generally I don't pay it much thought, but if I had to choose I'd say it does detract a little.
If you kill some of them the survivors will be resentful and think that killing is the only solution, since everyone does it, resulting is continued killings.
On the other hand if you just let them run off then they might end up killing someone weaker than you.
It's tricky territory.
I believe that one of the characters did in fact kill the entire enemy guild through a variety of traps and assassination.
However that was after everyone in her guild except for her was killed - a failed attempt at the same "solution".
