True, but think if it as a safeguard against Dms that think that just because they have neutral villains that they are making more believable campaigns. Also, eventually, Paladins may come into conflict with neutral characters and having a way of dealing with them in order to save them from their own inability to understand their folly.
And again, this is just a suggestion. I can totally see your point, but I thought this idea was atleast worth mentioning.
