Rule by force is the disease, who and how are symptoms.

As long as the majority remains silent while these people kill those people because reasons, we can expect to be ruled by the most violent on the block.
Absent rule by force people just do whatever they want, if they want to share, they share, if they want to be greedy f**ks, they get to do that, too.

Peaceful coexistence is less possible while toleration of rule by force is the norm.
