See THIS is a more interesting version of the conversation. :P The one I saw was something like, "Raise Dead creates an Evil creature, and creating an Evil creature is an Evil act, per the rules. Period, end of story."
And heck, even without exploring shades of gray morality and cultural constructs, having raised dead trap the soul of the person is more interesting worldbuilding. Even if it's a black & white situation, it drives home who the villains are.
