You are entitled to your opinion every one on here is.
And this is just my opinion.
I know you where talking about this game because of the scotish comment at the start but thats about all.
Reading the rest of your post you could be talking about some other game entirley.
I go as far as to say you haven't understood half of it if that.
His wife got him to Agree to a divorce while he was incarcerated on the previso he still has access to his Daughter.
And then she ran off with his Daughter in secret.
So he isn't pissed that his Sister failed to tell him where his Wife was as she was by then his X-Wife.
He was pissed because she kept quite about where his Daughter was and indoing so kept him out of his Daughter's life.
She also knew but did nothing when his X-Wife poisoned his daughter agaist him.
Even knowing his failure to find his daughter sen't him into a depressive drinking binge life style.
She and also his Mother and Father sill said nothing when Wife proved she wasn't gonna stick to the agreed stupid plan.
"What were they supposed to do?" I dunno try telling him maybe.
But aparently you gloss over that as if its not important.
True he treats his sister harsher than he do's his Mom, Dad, the actual main culprits in the scheme.
Or even his best friend who frankly he forgives far far far FAR to easily.
I have voiced that I think he wen't to far the other way with his treatment of his sister.
But she shouldn't get off scot free either.
Oh and "The MC was on a right rampage acting like a twat to his detriment while demanding revenge for his incarceration. He needs to accept it and just get over himself." well again NO he wasn't.
He was rageing however over the Americain Officer getting away with Murder and Attempted Rape.
While he was lock up for stopping him the MC had excepted his sentence.
He just hand't excepted them not doing anything about the American.
Hence the stupid and frankly Ludicruse plot by his wife/X-Wife to stop him persuing Justice against the American.
Now bearing in mind these are only a couple of the things you have got wrong.
Its really no wonder I'm struggling to recognise this game from your post.
Just Sayin.
