I'd say that Morgana was at least partway towards hating Uther when Morgause took her away because she was so terrified of what he would do if he ever learned that she had magic - "fear leads to anger; anger leads to hate; hate leads to suffering", after all. I wouldn't be surprised if there was also some resentment towards Arthur.

In The Nightmare Begins, Uther has a long list of people under suspicion of sorcery, has them arrested and is prepared to use their lives as a bargaining chip. He also orders a raid on the Druid camp, with everybody to be killed. Arthur is the one carrying out these orders, and he was the one who took Morgana away from people with whom she felt safe and delivered her back to the guardian she was certain was going to kill her if he ever found out that she had magic. Intellectually, she knew that he believed that he was helping her but that doesn't mean that there wasn't a part of her that resented him.

I'd say that the events of The Witchfinder would have served to further convince Morgana that she couldn't count on Uther to not kill her if he learned that she had magic, and probably couldn't count on Arthur either. We know from Guinevere that Aredian interrogated Morgana until she was close to breaking point but neither of the Pendragon men interceded on her behalf. From Morgana's perspective, they either knew and allowed it to happen or didn't care enough about her to notice what was going on. Neither option is an encouraging sign in terms of what she can expect from them if they ever learn about her magic.

Since the age of ten, she saw people executed for sorcery without the rest of the population protesting so she had no reason to believe that the people of Camelot would lift a finger to prevent her execution, despite her past efforts to help them when they needed it.

I'd say that she'd have needed less of a push to get her to hate Uther and the people of Camelot than Guinevere did to get her to hate Arthur & Co., but it wouldn't surprise me if there was a push.

Her healing bracelet could be potentially be influencing her judgement. We know that it's cutting Morgana off from most of her visions, and it's worth noting that, while past visions tended to revolve around threats to others, usually Arthur and to Camelot, the only ones getting past the bracelet now are ones concerning Morgana's interests. That thing has concerned me since Morgause first gave it to Morgana.
