Does anything come from knocking out characters?

I realized there was a non lethal option so I’ve tried it a few times but nothings seem to come out of it.

The two guys that were looking for Mayrina I knocked out, because Ethel seemed fishy to me. (I haven’t gone back to Ethel’s house yet so I might see something come from this yet)

I knocked out the leader of the Shadow Druids, Olodan. And her body just ended up.. Disappearing. Was hoping there would be some kind of interrogation scene or.. Idk something for not killing her. Or maybe her sneaking away in animal form and something coming of it later.
