Is There a Sentient Evil in the Lord of the Rings?

The idea a, am i neutral evil? Or am i my neutral good? In reality, we have multiple allignments in ourselves at all times. And it's about nurturing the alignments that are the person we want to be. I mean, there ther aspects of humanity, a in a role in the world that would seem at least lawful evil, ifit were neutral evil. There're other things that that are not so so it's one of these things that it works well within a game context, as long as you're not thinking too hard about it, i guess.
