I also do not believe in the devil or hell... I believe in low spirits and entities, which are sometimes called demons. And about hell, hell is what we have created in our lives when we are disconnected from our Source. I do not believe there is an eternal place in flames waiting for us to join
... I believe both heaven and hell are states of consciousness. Maybe we need to experience both to be complete.
I believe we have been both victims and victimizers in the past. I believe it would be a natural evolutionary process. Just look at our history and what we have done to each other... What we still do to each other sometimes. Those have been the demons and this has been the hell created by such consciousness.
Maybe now we will be able to experience a higher state of being and leave the demons in the past... Or maybe not.
