You might explain what is going to have to be done to my 'soul' when I get to heaven that will allow me to 'be happy' while I watch or think about my fellow man and loved ones suffering 'back on earth'.
If you extract those concerns and loves from me, such a soul is no longer 'me' but a frightening generic thing, and to claim that this is what souls truly are is to claim that all the "me's" on earth are an illusion, a game, a vanity and a cruel hoax.
"Haunting" indeed is the perfect word for such a belief system.
