Also, this all depends on your POV. As a christian that believes in the Holy Spirit in you, you cannot be possessed. For Hummer's belief, anyone can be taken by dark forces. And for another "good vs evil" standpoint, tygar pointed out that LDing isn't inherently good or bad. It is how you use it. New Jedi Order like.

I can say this though, know what you believe. If you believe something to be good.Do it, bad don't do it. Something nuetral, use it in a way for good. If you are honestly seeking the truth you will find it.
