Yeahh, if I remember right, he had been essentially brainwashed by the church since a young age to do whatever they wanted and they manipulated him as they pleased. MC's mother assumingly got to break him free of some of that, so suddenly losing her would've been devastating for him, and probably instilled even more religious indoctronation on how he's the cause for all this and needs to repent, etc.
I also vaguely remember seeing flashbacks of their past lives where he always did try to get to her/save her in time, or was utterly devastated when he heard of her deaths.
Not necessarily trying to argue or defend him per se, I don't particularly care enough to do that, just wanted to point out what we know so far (and what I remember).
I just don't like them especially the Father, I'm sorry but even after knowing he loves her daughter, but that multiple lives she lived through but not a single one where he was present and there for her.
There may be an acceptable reason, but for me that reason will never be enough.
You were given multiple chances in different lives to make up with her and be by her side to protect and care for her even if you won't admit being the Father, but you just stubbornly try to hide and ignore all your daughter's advancements, it's freaking frustrating! She lived those lives experiencing hardships including her being fatherless! That's some emotional damage! She had no one to lean on those lives, and he was just there! Being busy with his self pitying and downing and mourning! Di kana sana umiyot yawa ka!
