I'm not sure if someone's suggested this or not. From what I checked it's a fresh idea.
I find it disturbing how a small group of high level players can kill others at will after acquiring the skill "murder".
Some ideas which should deter murderers:
1- A debuff (called "guilt" or something along those lines) could be implemented which would cause the murderer to play with reduced stats (reduction of 5% or 10% for every victim).
2- The murderer's "guilt" can be detected by rangers and this would allow the ranger to kill the murderer or gather a village mob which would hunt down the murderer, the reward being extra LP, the murderer's items and perhaps a buff such as "duty" or "revenge" which would allow the recipient to earn LP faster or increase his stats permanently.
3- Ranger reputation. The idea of bounty hunters earning a reputation for themselves which would allow them to show off their skills (to attract customers) seems like a cool idea. This would create an abstract "law" in which anyone can be a criminal but runs the risk of being a hunted outlaw in doing so. Also, the rangers should be allowed to write contracts which state that certain items must be given in return for a murderer's life, after which the said items would be reserved for when the ranger completes his task.
4- The belief system should act an important role in this, where a hearthling that respects life would receive a harsh penalty for killing another hearthling, but a hearthling that worships death earns a smaller penalty, if not none at all.
5- With respect to point 4, death worshipping hearthlings can create their own "outlaw settlements", which would give them a chance of surviving with all the rangers/bounty hunters around.
