However, he already does have a conflict in that he's driven by his impulses sometimes. He becomes completely controlled by them, or consumed by his flames. It's just like how he beat up the kids at day care, he relentlessly went after them. That's why when he first got out of control, he remembered that incident and was afraid.
Now, later on, something might happen to split Rin into his demon impulses and his kind self. The inevitable shounen cliches would happen, but I trust Kazue in her impeccable delivery.
