No need to be so violent.
You can knock them out and then loot all items and gold.
The next day they will have a new inventory waiting to be looted.
Worse, they remain at 1hp from the previous knockout.
Use a bit of stealth and there is virtually no consequences.
Fair point hahaha
In my own defense one I killed was a goblin trader, and the other was the halfing when I got angry that she would let me into her secret storage room. So.... I blew it up.
