It's true that there are indeed parent/s who will blame their child. And the father certainly loved his wife more; I see this happen a lot because the father (usually) don't feel the same closeness to their child as much as mothers do who has to carry the baby and give birth to.
From what we've been shown so far, I don't think he is to blame for what happened. It was all an accident. However, that doesn't mean he can torment his child for what happened.

Maybe I’m the only one who thinks that the backstory isn’t shitty at all? Even in real life there are parents who will blame their child. I think the father loved his wife more than his own child. I wonder if he ever was a good person.. blame everything else expect himself.
