No, guys, this post is not against permadeath.
This post is about ease of killing bodies you met in the world, and impunity of that.
I dont think that we need limit it, i think there must be a way, where knocked out body can be more usefull, than dead body and murder scent.
For example, shackles equipped to knocked body will leash him to you, like an animal, he will follow you, and jump on your hearthfire with you. That will leave scent of slavery.
Shackled body cant log out, cant jump his hearthfire, and have limited access to claim as owner has.
Slave holder can do anything with slave: force him to build house, harvest minimap of crops for freedom, or victim can think that logout will save him, but can be killed anyway.
So, with that mechanic there will be:
1. No need of killing bodies, you can have more benefit from it.
2. If you met 10 bodies that will just smash you - you can have a chance to be saved.
3. Your friends can track you, and save you at least.
All this inspired by thoughts, that killing is not so easy in real life: there's law, conscience, religion, other thoughts that will prevent it.
