While I like how much thought and energy you are trying to put into 'bettering' DayZ, I dont believe a system like this can ever fly.
It is just not possible to properly implement something like this in a universal way.
Just think about the group of 'bandits' that moves around together.. they will perform all kinds of 'heroic' deeds on each other too..
Or the other extreme, a player who miraculously manages to kill the entire group that tried to ambush him in self defense..
And and and..
And personaly I dont think that it would be an improvement for the game. Anyone should be free to do whatever they want to do, with no system that tries to lead you into any direction what so ever..
So, a thumbs up from me for the work you put into a well presented feature suggestion.. but also a downvote due to impraticality and because of my opinion that a feature like this has no place in DayZ.
