There is no need to get the message, it is just a player opinion biased by their own experiences and view of the world, I respect it but I have a completely different (and also biased) view and experience in such matters. Holding grudges/hate and imagining what would happen if their decision have been different and being over confrontational never leads to good outcomes and in that I completely agree with sis, having an open mind and leaving the door open seems imho a much better path for everyone involved, after all the past can't be changed, only the future can. That doesn't mean "we" can't get hurt or angry by those decisions, but hate never, too much of a strong word in this situation.
With that said I went in 1 of my 5 save paths being confrontational and burning the bridges of reconciliation but just by pure curiosity of what that path will lead in terms of content in upcoming updates.
Edit : Sometimes I wish we had a "Facepalm" post reaction instead of "Wow" for some oversimplistic ignorant remarks I see in this threads

I don't even see the point to reply to them, it would just end up in a pointless confrontation discussion because we both are too stubborn to let go of our views
Confrontations are different from letting go.
Sure, I went, and always will, take that choice while talking to parents.
There is nothing good from being in toxic relationship. In my personal life (as in, actual life), I broke my longest and best friendship over my ex-friend being all kinds of wrong (racist, sexist, list goes on).
My life blossomed since breaking that friendship and leaving him in the past.
Now, did I argue with him? No.
But game, so far at least, wouldn't let me break relations with family unless it's confrontational.
I went 3-2 on my pick-how-you-feel-not-points choice.
MCs family was insanely toxic for his life, in some circumstances thry would have mentally scar him for life.
They valued their job over their son.
It is not even hatred (though I personally would absolutely feel it), it's moving on with life.
It's choosing to live a life where Templars don't dictate his job, his girlfriend and his future prospects.
It's choosing to live own life, instead of a fake, gifted one.
I completely understand why some people would be forgiving to them, not burn bridges (always an extreme, final step), but I simply fail to see why feeling hatred towards someone who fucked up your life beyond repair is seen as facepalm worthy.
Kari's advice was perfect in this chapter. MC wants to live life of his own. So go and do it. Elves were first step. Human world, job and so on is next.
Will it be hard, messed up and so on? Sure.
But will he be able to create something honest? I believe that chance far outweighs the risks of distancing himself from (strongly proven) toxic family environment.
