No, seriously. . . I'll have to fall back on one of my own creations.
Thanator, the god of death in my Leshan campaign is not a 'bad guy' deity. He is represented by a fighting order called the "Undefiled" whose job is it to send Undead back to the boss and to protect the sanctity of burial grounds. We had a warrior priest of Thanator in my last RQ campaign and he made for some interesting roleplaying instances, especially when he was stopping the rest of the party from looting what he declared to be "honorable dead". He would allow them to loot monstrous opponents and those without honor, such as ambushing bandits and the like, but foes who challenged and faced the party head on were off limits.
