According to what I've been reading of theosophy, wanting to do something evil is just as bad actually doing it. When you want do to something and you don't, the only thing holding you back is fear of consequences. If there were no consequences, you would likely go ahead and do it if that's what you really wanted.

It there were suddenly no law, there would be a lot more murderers in the world, among other things. But it wouldn't be the removal of the law that turned them evil.
