Sooo there doesn’t necessarily have to be a reason for forgiveness. If an abuse victim wants to forgive, if an abuse victim still wants to reconcile with their abuser, that is okay. That’s a valid way of responding to abuse. It’s equally valid to be like Natsuo and never want to see your abuser again, or like Shouto and want to take a “prove yourself to me” approach.
I don’t personally think there is any secret behind why Fuyumi and Rei want to forgive him. Rei’s forgiveness also is not reconciliation at this point–she does not want to see him because she and her therapist believe it would be dangerous to see him. Fuyumi wants to reconcile and has forgiven. I think it’s just how they’ve responded and are coping with their abuse.
All the Todoroki victims are coping in different ways. Touya, presuming he’s Dabi, is coping in the least healthy way in that he’s lashing out in a way that hurts others and himself. The other four are all possibly healthy for them–there is no one right best way to respond to abuse. All that to say there might be a reason behind their forgiveness, but I don’t think there needs to be beyond that’s just how they are coping.
Anyone who judges them for forgiving him, though, needs to grow some empathy. Abuse steals power and worth and choices from a human being; letting a victim decide how to cope with it (in a non-destructive way) is empowering. Being told you need to forgive and being told you should never forgive are just as destructive.
