Eating human remains, awesome idea!
I was thinking something like you get x amount of "feed" points for eating human remains. The feed points could stack to give slight buffs or even neat flavor text (im thinking Black Plauge bow), even maybe transforming the player into a zombie for a time.
Feed Points 0-10: +2STR / -5INT
Feed Points 10-20: +5STR / -5INT -5DEX. Says "Need to feed" or something on hit attacks, or corpse consumption.
Feed Points 20-30: +10STR / -10INT -10E+DEX. Gets a sort of vampire form, imune to psn.
Well you see what the idea I had here was.
