Also, we don't have to let this happen too often. I think scarring would only occur when player killers don't actually kill their target but get it very very close to death and just leave it lingering there or something like that.

That's a good modifier.  Hmm, maybe they have to use some kind of poison too?  Something that delays injury recovery or a certain amount of hit point restoration until it's nullified or wears off?  So, if they did twenty damage to you and ten was the poison's strength then you could only recover ten hit points until it wore off.  There's lots of ways to work this.
