It's the feeling of power and control they're after. They feel like a god ripping away innocence and corrupting the weakest and most helpless among us, invading their bodies and desecrating them. But that's not enough...they need more power, more control, more corruption. So they go into politics, or the church, or children's clubs or services where they can corrupt society, strip away its value and self worth. They are evil, broken, wicked things.
