That is a much more complicated question than most people think. In order to answer it, we have to figure out a few things.
First, believing in the Christian Hell implies a belief in the Devil, who is a Christian Deity. Believing in a Christian Deity implies that you are Christian.
Witches are not Christian. We have no place of eternal punishment. We understand that it is natural and normal to have a positive and a negative side to ourselves. Our Gods reflect this by being more human than the Christian God.
We do not believe in any form of Ultimate Good, or Ultimate Evil. We understand that we each carry both within us, and it is our choices each day that determine the person we are.
The question I have for you is, if the Christian God would condemn you, or anyone else to an eternity of suffering, simply because you didn't worship Him in a specific way, is that really a God you would want to follow?
If the answer is no, then you would not end up in Hell for being a Witch.
