What happens if the main priority of the thing you love is to say: "I hate you, kill yourself. If you don't love me, then you should kill yourself. Also, I hate you, kill yourself." ?

I feel like, when the demon is wearing the skin suit demanding you love them and to kill yourself if you don't, the problem isn't that the people didn't fall out of love of something they once loved. They are just refusing to love the thing that murdered it.
