(this is just my personal opinion and belief)
I've been living several human lives for now - tell me, is this heaven?
Hell is in the minds of believers - when faith speaks of God!
The devil I know is an antimatter being who can change and contain a lot of love and compassion, but he doesn’t want to be persecuted, so he can affect matter and he can destroy it.
He works for humanity not against him and he does not work wars and differences in skin color.
