2) Alright, fair enough, if that is the case, then let me explain. In D&D, Good and Evil are absolute. So certain actions will always be evil, like torture, rape, murder ect, no matter that the situation is. BoED is the Book of Exalted Deeds, which covers this
Another one of those "always evil" acts it describes is magically changing someone's alignment. A couple pages later, it offers a Good spell to change someone's alignment to Good.
Short version: the BoED isn't worth the paper it's printed on.
