If you want benefits, become a Hero.
Exactly. This request is a response to those who have asked for the capability for their characters to die, not to create another risk/reward system. I guarantee this change would be instantly rejected if it were a fundamental change to the way the game is played. As it is written, if no players participate in it, the game does not change at all. The incentive to do it comes from the player and the player only.
Also, Indirik, I think I included that it would be private information. Sharing it would also fundamentally alter the game, especially for infils. As has been stated numerous times, infils were
not created for the purpose of killing nobles. A kill, even with this option, should come as a surprise. Potentially a horrific one (RP: "I... I didn't mean to kill him... Oh god, what have I done?"), though players are free to RP as they wish.
