Kinda agree on the points made about Kinu tbh, though with my character it kinda fits. He's a powerful black mage who faces constant danger out there in the world, and that's the only way he knows to protect his friends and children. He hasn't had the time nor can he make the time to settle down and be with family, because he must keep searching for Kasyrra and stopping her corruption of the entire world. For all he knows, if he stays just one week with his family to learn how to be a father and a husband the way those roles are meant to be, Kasyrra could win. Every time he gets to fight Kasyrra or her minions, he knows he's putting her more and more on edge, as while she's toying with him, and she wants him to grow more powerful before consuming him, both Kasyrra and my PC know that the moment she'd best attack him is when he's just slightly weaker than she is, and at the rate he's growing, that moment could pass anytime. Kasyrra must be aware of that, too.
So while yes, I agree that there should probably be options to be a proper parent to any of the children you can potentially have, I also can understand how any PC would be incapable of it during the game, as they're generically young, for all we know parentless, and wanderers. All of their relationships are based on lust, and while they may say they love someone, they can't get to know them in day to day life beyond threatening situations.
In short, the PC is immature, and that explains them failing at parenting, just as they fail at having a serious relationship with anyone.
The PC in CoC was much the same, and the most parent-worthy thing you can do in that game is train Helspawn to be able to survive, teach her moderation, and teach her not to be a slut. Kinu was already trained in combat by her mother with or without PC's help, she knows moderation as part of the Kitsune culture, having to be exemplary to others, and while she technically is a slut like any other kitsune, she's not rushing to become her mother, neither hime Kinu nor hippy Kinu. The PC couldn't teach her much more than that. Kinu needs parents to be there for her, and the PC can't provide during the game. Provided both PC and Kinu survive in the long term, sure, I can see the PC starting to take the Kitsune culture more seriously and actually trying to be a parent.
