Mammon theory #1 (updated)
(I mentioned the theory to a friend after I have posted it and she pointed out evidence to edit my theory slightly and make it better. )
The ring on Mammon’s pinkie finger was the one he planned to give the human witch he’d fallen in love with. He planned to give it to her to propose and she rejected him and most likely dumped him. This was a woman he’d fallen completely for and he wanted to stay with her forever. And after she dumped him, Mammon was heartbroken. He kept the rings due to both his greed and needing a reminder of why love is trouble. However he can’t help but continue to fall for anyone who shows him the same kindness and affection. He’s a greedy demon after all. The witch’s name was Grisella. Mammon seems afraid of her in the game but that is because of the feelings she made him feel. She wanted to remain friends but he may not have been able to accept it.
