That's exactly it actually. They say the creators contradict themselves because Cloud is said to be happy living with Tifa but not SHOWN to be happy.
They're forgetting phase two of the sentence, where that very happiness makes him feel more guilty and paranoid. So before AC, Cloud's happiness leads into a spiral of doubt and worry.
They also think we contradict ourselves by saying Cloud's promised land is with his family because if that's true "Why does Nojima say problems will still happen and they might not work them out and the kids have to intervene?" (which isn't quite what he says
)
You're right, happy does not mean no problems, everyone has them.
Surrounded by his friends and family, Cloud realizes where he belongs?
Add to that 'I was sure of one thing, Cloud would be with Tifa, etc.'
Contradiction = no.
Really, even a place of supreme happiness needs to be worked for.
YES!
I'm so glad to be on the side that makes sense
In short: Cloud's real problem wasn't his guilt, or that he was alone, but that he felt he must be alone, he must not 'push' his problems on people who only want to help. As of ACC, he realizes he can let them help, and will be there to help them.
And yes, Cloud seemed happy enough at several points during CoT.
Like at the end when he smiles.
Fake smile. Thorsmote, etc.
