I'm really curious about the Uther things you mentioned?
Ahh hey! Yeah I can talk on that a bit (for context, I think I said that I do find his character intriguing and that my opinion on him has evolved quite a bit, influenced by mostly disagreeing with what a lot of people tend to say?)
So the thing about Uther is that I feel people tend to either go "He's evil, everything he does at any given time is evil, I hate him and there is nothing more to it," or they go "Oh but he loved his children!!!" in a kind of, redeeming-quality-kind of sense. I'm somewhat hyperbolizing, of course, but I do think fandom tends to a very black and white view.
Don't get me wrong, I hate Uther. I hate Uther with a burning passion, and I love to hate him. He's terrible. But I do think the show actually did go to quite an effort to make him complex beyond a simple "tyrannical son of a bitch" (that he was) or "Oh okay but he loved Ygraine and his kids 🥺" (which he did!).
Of course he is terrible. He murdered hundreds if not thousands of people over the guilt he could not bear to live with, that was, in the first place, the consequence of his own actions. I do believe he didn't know that the price would be Ygraine's life; he was still willing to sacrifice someone's life. Which is very Uther. Yes, at the root of that lies grief, and at the root of grief lies love, but the thing (and also imo the crux of Uther's character) is that being capable of loving people doesn't somehow, magically (ha. sorry) make you less of a bad person.
Terrible people can love other people. In fact, I think you'd be hard-pressed to find people no matter how atrocious their actions, who don't have people they love. And most people don't set out to "do something evil;" Uther, in all his atrocities, always had justifications to himself.
I think it says a lot that despite the brutal war he wrought, he was by and large not considered a bad king, per se, by his people and allies. We could dismiss all those instances where the show makes a point to reiterate this as fear of speaking up - and I'm not saying that didn't play a part - but I think that's making it too easy. There is a whole other essay on propaganda and how the war on magic worked, but I'll get to that another time. My main point is that, as uncomfortable as the thought may be considering just what horrors he wrought, he wasn't a frothing, mad bag full of cartoonish evil.
That doesn't mean that he "wasn't that bad, really." Which kind of brings me to the other side of things, the way people like to throw "Well, but he loved his kids," into the mix as a kind of. I don't know, counterpoint to the "tyrannical son of a bitch" side. And like, the thing is, he did. The thing is, that doesn't change a thing.
Yeah, Uther loved both Arthur and Morgana. We see enough proof of that through the seasons, whether it's in the Excalibur Episode where he fights in Arthur's stead at any cost, or in Le Morte d'Arthur where he openly weeps, or with Morgana in various instances to a degree where some people think he loved her more (and again, yet another essay on how his love for Arthur is tangled up so much in his guilt and the hatred that caused, but I digresss), not least in how her 'betrayal' broke him.
Ultimately, though, he also put Arthur in harm's way again and again. He certainly rarely ever told him he loved him, to the point where Arthur is shocked to hear it. He puts his children in chains and locks them away and drugs them and threatens them in all manners, he lies to them and hides the truth from them (Ygraine/Morgana's parentage in the first place) to the detriment of their well-being, and so on. His love is conditional. His love demands obedience and submission. We could argue until we're blue if that's really love in the first place, but at the end of the day, it doesn't really matter all that much.
People can love other people, and it can be entirely inconsequential, because frankly, most parents love/"love" their kids. That doesn't mean they're automatically good parents, or even good people. In Uther's case it really isn't a redeeming quality at all. It just makes him complex and interesting and multi-dimensional as the villain/antagonist. Because it makes us grapple with the really very unfortunate but inevitable fact that even terrible people are still people. They aren't some removed monster that no one can ever relate to. They love and they laugh and grieve, and they can still turn around and burn people in their frontyard on the daily without missing a beat. They can be willing to die for their children and threaten violence and exile in the next breath.
I think with Uther, at the end of the day, for me it's really both. His atrocities started out of love, and his love is steeped, inevitably, in the violence and twisted moral framework of his character; it's not an either/or thing at all, it depends on each other. And he is a goddamn son of a bitch, of course, even if every once in a bluemoon he still sheds honest tears for his unfortunate children.
