If God is far more powerful than Satan then why would anyone want to worship the one who is much weaker?

I wonder this all the time. Why would someone want to be an atheist or a satanist or a mason, etc the list goes on and on. I will never understand it at all. If they keep it up though and do not confess it they are living in mortal sin and if your living in a state of no grace, then all of these people are playing with fire.
