Witch: I'm Addicted to Sucking Him

The witch is trying her best to save me in order to let me die. I was forced to sign a contract with the witch, borrow her power, and sacrifice my soul. When her soul is exhausted, she will kick me away and tell me to get out. But after just one use, the soul was about to bottom out. It wasn't until I stood on the piles of werewolf corpses and raised the corroded paladin sword high that I suddenly became curious. Is it the witch who wants to consume me to death, or am I trying to take advantage of her?
