Rhemus, I'm not talking about emotional commitment to anything. What I'm saying is that in order to perform an Unforgiveable Curse, the curser needs to really want to perform that curse. They have to have the will behind it. They don't necessarily have to have any kind of emotion to kill a particular person but they need the will to perform the curse itself. Wormtail could perform Avada Kedavra because he had the heart to do it. Cedric was nothing to him which is probably one of the reasons why he could kill him. It's not the want to perform a curse on that particular person but a want to perform the curse in general. You have to have a large amount of hate and want to perform pain in order for Crucio to work. It doesn't matter who's on the receiving end of it.

I don't think the Death Eaters are his minions. V definately gets his hands dirty so if he had minions, why would he bother to do anything? I do believe that there are levels within the Death Eaters and say, Bella is at a higher level than Goyle. Besides, the Mark is V marking people with similar values as he has. The Dark Mark shows that this person values the Dark Arts, has disdain for muggles and, essentially, wants them dead and strives for a pureblooded world. Those are all values he holds which makes those with that Mark equal.

What does a patronus and ridikkulus have to do with anything I was talking about? Did I even mention them in my theory? That was out of the blue to me.

This is slightly oxymoronic. How can you think she's telling the truth but be lying about it? She's either telling the truth or she's lying. She can't do both at the same time. She might just explode. I think Bella is one of the supreme rulers on how to perform one of the Unforgiveable Curses so I have a tendency to believe it when she says that one needs to really want to cause pain (again, just the act of causing pain, not causing pain to a particular person. The Unforgiveables aren't prejudiced) in order to perform Crucio. What I was saying was that even though Harry felt so much hate and so much rage and anger, he didn't have it in him to cause Bella pain. It doesn't necessarily make him weak, just not the torturing type.

By the way, thanks GinnyWeasley! I was afraid that my theory was just a bunch of rambling and I twisted things around so that it only made sense to me.
