I find that as of Beta 23.3 on Minecraft 1.7.10, I am able to hit allied NPCs with a Morgul Blade and inflicting the Wither Effect on them. Although they don't take damage from the sword, they end up dying, and the durability of the Blade (or my alignment, for that matter) is not affected. Is this intended?

Be it intended or not, it's a very good way of backstabbing your own friends, if that's what you're after.
