Asazel (the correct pronunciation as it is what he calls himself) must be released. Because of his binding, he suffers year after year on Yom Kippur.

I have spoken to Asazel before. Only once. He is very powerful but he is a slave to the Hebrew magicians that benefit from his binding. He is not "evil". He is a powerful spiritual being that was never human (or anything LIKE human. He is largely friendly but, like most of his ilk, doesn't like to have his time wasted over trivial matters.

He does not exist to be controlled. Sadly, though, this is what has been happening for millenia now.

He must be freed.
