Satan is a relatively modern Christian mythological concept, combing images of fallen angels, biblical adversaries and popular pagan gods like the horned gods Cernunnos and Pan. The gods of the old religion become the demons of the conquering one. The Church was trying to sway pagan believers to the new faith by telling them their gods were really devils. For the most part, witches do not believe in the Christian cosmology, so they don't even believe in Satan. In our worldview, no one tempts you or forces you to do things.
Witches believe in responsibility.
No one is trying to steal your soul. Nature is our scripture. Things live, die and are born again in other forms, like the changing seasons. No one sits in judgment, but what you put out, good and bad, comes back to you. This is called the Law of Return by some traditions, or the Law of Three, feeling what comes back to you is amplified three fold.
