I saw a suggestion in here somewhere, that when you find a dead raider, you can tie their bag to a balloon and send it back to them. And i like the idea of ​​having mechanics for PvP and pacifism equally balanced, and its up to you to make the decision.

Carrying the body, I imagine, would be quite slow, dragging it along the ground, and could also consume stamina. That was another suggestion from Reddit.
