noone seems to have given you an answer yet, so I'll give it to you straight, the worst possible way to give anyone anything.
best case scenario, your soul is subject to unimaginable agonies over a period of several hundred years, your screams slowly changing from shrieks of insane agony to shrieks of insane boredom. the pain no longer hurts, it is simply banal. you have felt everything it is possible to feel and now all that is left is the mad hope you will one day feel something, ANYTHING new.
on the day the last fragment of that hope is burnt out of the grey, tattered mess that was once your soul, the Prince of Pleasure will consume it, consigning everything you have ever been to oblivion.
worst case scenario's basically the same, only because you ate a bunch of souls yourself in life it takes a lot longer.
