"However, when she asks from Uther to accept it, he denies it. This crumbled everything inside Morgana. To her, Uther was now a hypocrite, one who doesn't accept his own flesh and blood in order to hide his own sins."

I'd say that it was more than Uther being a hypocrite.

In Season Two, Morgana was terrified of Uther finding out that she had magic because she believed - rightly or wrongly, we'll never know for certain - that Uther hated magic more than he cared for her, and that she could expect to be burned at the stake if he ever found out about her magic. She was living in fear and feeling alone until Morgause took her away from Camelot, after the person she believed she could trust with her secret had just poisoned her.

When she returned after more than a year away, Uther doted on her. During her absence, he had his knights scouring the country for her, and didn't give up on her, no matter how many men he lost. Depending on how much she overheard, she doesn't just know that she's his daughter, she knows that he was prepared to use magic to save her life, which points towards his love for her outweighing his hatred for magic. I doubt that she considered telling him but maybe his words gave her hope that, if she was discovered to have magic, Uther wouldn't hurt her. Maybe she didn't need to be so afraid of him, after all.

As well as this, Morgana has commented on more than one occasion about feeling alone. She lost a father she loved at the age of ten, and since then, she has had a home in Camelot on the strength of Uther's promise to Gorlois, a promise that he has threatened to break in the past. Uther is not above reminding her that she is beholden to him for taking her in whenever they disagree. Morgana characterised her position in Camelot as that of a guest. That's a dreadful way for her to be made to feel about the place that has been her home for at least half of her life.

Finding out that she was Uther's daughter meant that she had family she never knew about and I think that's something that was very important to her.

She wants Uther to tell the truth about her paternity and he refuses. Everything he has told her about how much he loves her and how important she is to him must have seemed like empty words and she also lost any hope that he might have been prepared to love and accept her for who she was, magic and all. If he doesn't care enough about her to be willing to claim her as his daughter, she has no reason to believe that he cares enough about her to not murder her if he learns of her magic.

I don't think that she was thinking in terms of her status if Uther acknowledged, much less of becoming Queen. Morgause was the one to point out to her that her royal blood meant that she had a claim to the throne. Morgana doesn't seem to have considered it at that point.

However, when Uther refused to acknowledge her, she wanted to punish him for it. She knew that he didn't want to reveal the truth about her paternity for Arthur's sake so I'd say that part of her motivation for becoming Queen was because the succession was Uther's reason for disowning her. What better punishment for Uther than that the daughter he refused to acknowledge takes the throne from the son whose interests he put ahead of hers?
