Those are some really interesting questions to think about!

*Why has Uther changed so dramatically?

I think that, as you said, seeing Arthur ruling Camelot in a very different way must really have embittered him (still, it doesn't make sense that he would try to kill him).

*Why did Uther go after Percival first, not Gwaine or Guinevere or someone else?

I actually think he just went after Percival because it was convenient ; because Percival was finding himself alone in the armory, which appeared to be Uther's hiding spot at the time.

*Why did Uther not ask about Morgana when he spoke to Arthur?

This might be an unpopular opinion, but to me it always seemed like Uther sort of preferred Morgana over Arthur. Morgana couldn't do anything wrong in his eyes, whilst he constantly saw Arthur as a failure (perhaps this has to do with the fact that Morgana and Uther's characters are quite similar?).

Therefore I believe the scars Morgana's betrayal have left on Uther must've been extremely deep, and just as he used to refuse to talk about Ygraine, he now refused to talk about Morgana.

*Why did Uther not haunt Morgana after he was released?

Perhaps he was bound to Arthur as he'd been the one who'd released him? Or else I would say because of the reason I stated above.

*Was Uther actually trying to make Arthur release him?

That's a difficult question ; I don't know if Uther would've known about such consequences. Maybe it just happened, but that wouldn't explain why he would initially confess his love to his son and then turn into a raging psychopath afterwards :/

*Why did Uther not care about Arthur kissing Guinevere in Series 4, but suddenly tries to kill her in Series 5?

Uther was very weak during series 4, he might not have had the strength to object? But remember in Queen of Hearts, when he initially believed Gwen and Arthur's love to be 'the folly of youth'? Maybe he didn't consider that his son would ever marry a serving girl, and therefore wasn't bothered?
