No one likes Nazeem, not even his wife. It'd be a favor to everyone in Whiterun to get rid of him. But you don't have to kill him in a dark alley, instead send Nazeem on his own exciting quest across the breadth of Skyrim! Maybe in your travels you might cross paths, but hopefully not.

(This is my first attempt at modding and mostly just the result of tinkering. Let me know if this somehow causes horrible CTDs or other issues.)
