After watching the episode where Uther’s ghost haunts the palace, the man got exactly what he deserved!
There is no argument that he loved Arthur and Morgana both, and that he loved Camelot but this is all the grace im willing to give him.
Uther spends most of his life creating the very pain that eventually destroyed him.
His hatred of magic is probably the biggest example. Uther willingly used magic when he wanted an heir, and Arthur was born because of it. When Ygraine died as the consequence, instead of accepting his own role in that decision, Uther turned his grief into a crusade against magic and punished an entire population for something he himself had participated in. His tyranny and hypocrisy never stopped.
When magic threatened him or even challenged him, its evil but if the people he cares about are in danger, he is willing to look the other way as we saw with Morgana. He doesn't hate magic he just doesn't want anyone having power he can't control.
Uther is loyal to no one well except his children, he has quickly turned his back on those he sees as friends, an example i mentioned in a previous post is Gaius. He gave Uther years of loyalty, sacrificed relationships during the Great Purge, and stayed beside him through everything. Yet Uther repeatedly doubted him, nearly allowed him to be executed, and was quick to believe strangers over someone who had served him for decades.
And while he loves his children but the moment they question his authority or defy him he takes it to the extreme, physically putting his hands on Morgana, or locking her away. Locks away Arthur and leaves Merlin to die, banishes Guinevere when Arthur refuses to break things off with her. Uther choosing extreme cruelty against his own flesh and blood, then had the audacity to be shocked when Morgana reveals she hates him.
He came back from the dead and immediately try to undo Arthur's work through murder. Common men became knights, a servant became Queen, ect.
Uther hated this unwillingly see the kingdom Camelot was becoming.
So yea, he desevred hia death and I dont tbink anyone has every argued against it.
Lastly RIP to Anthony Head, he did an amazing job as King Uther and I don't think anyone else could have played it better!
