I don't think you understand the way I 'control' them, Sam. Most of it is suggestions. I only force them to do things if it's seriously something that freaks them out, like going near angels and stuff. Mostly, it's just pushing them the right way. Carefully. They go pretty willingly. It's kind of like training a dog, or a cat, or something.
I'm not as freaky as you, mister 'mmm, blood is delicious'.
