Murder or stun? (Dishonored 2)

If you kill then flies will fix eggs in corpses, and then zombies will sleep

I'm talking about the overall impact of the player's actions on the ending.

Somewhere read that for the level you can kill 3-5 enemies, but it is not accurate, and it seems not to be a bad ending. And so yes, you have to go without murder for a good ending.

As little as possible you kill - a good ending. You're all on the right and on the left - bad.
The number of murders directly affects the ending.
