Wow, if you're not a lawyer, you really missed your calling.Animating piles of bones is evil, but hacking and slashing monsters into piles of bones is heroic? Sorry, I don't buy it.
"Ladies and gentlemen of the jury, the prosecution would have my client convicted for desecrating the dead. But consider this highly relevant fact: police officers use guns to shoot criminals. See where I'm going with that? I am to believe that training someone to use a weapon isn't inherently abhorrent, but defiling a corpse somehow is? Balderdash! Land of the free indeed!"
You even got XP for that load. I'd hire you next time I get caught digging up a grave.

In all seriousness, is the distinction really that unclear? Certainly you can use a sword in an abhorrent manner, but the mores embraced by civilized people do tend to condemn the idea that a person's remains are abandoned property that anyone can lay claim to and repurpose.
