He is dead later in the game... maybe you only need to wait?
You need only the key from the pouch in the room rigth of Thelyron, after putting Jakes wife in the prison.... maybe you can kill him, without Problems and the game don't break the storyline. But I don't know if he is unkillable.
Or maybe you can kill him and bring him alive back later?
