You have no ideas of the effects or cycles of abuse. Hayashida was abused, bullied and hit at work every day so guess how he dealt with it? He knew it was wrong and it's good it ended where it did. Something like "don't let me be any more of a monster than I already am" like pretty deep. No one is saying forgive. They are saying to understand. Both of them need love and support and maybe some therapy but to me I empathize with Hayashida's journey to becoming who he is, recognizing what he was doing and how he would never be the same.

You're making abuse out to be a simple thing. By saying 'don't let me be any more of a monster than I already am' he is putting the blame on someone else than actively trying to recover on his own. <<he rather take away his punching bag then work on himself. Even after, we don't see how he deals with the fact that he was abused and was an abuser. Abuse does not stop that easily. NOBODY is saying that he isn't trying.
They are saying that he should do something more proactive about it. That it won't be magically fixed. It's not as simple as you think that just because you WANT or WISH for it, it would magically be better. He has to ACTIVELY work for it. The fact that he held on to the pictures for so long after, showed that he HASN'T moved on from what he did and he SHOULD. Especially before moving on to a new relationship or else at least still be in therapy for it. What he was doing before the new guy came along was still him just avoiding someone in case he GETS abusive.<<Still trying to pin the blame on someone else. Instead of going after the problem itself. And that's not healthy. Recognising a problem is all well and good but does nothing if he never tries to help himself.
Am I the only one who still thinks Kan-chan needs some kind of therapy? I don't understand why everyone is suddenly forgiving his previous abuse just because we found out about his troubles at work. You don't beat the living shit out of someone because things are going badly. Who's to say he won't get frustrated again someday and start pounding on his new boyfriend? That kind of mental damage doesn't just "repair" itself. I know everyone wants a magical happy ending, but I can't imagine that Kan-chan is suddenly a mentally healthy person with no violent tendencies. I was hoping we'd see him grow a bit more as a character rather than get "fixed" by a new man who was willing to overlook what he had done in the past.
