What are your favorite examples of antagonists that change and grow throughout a story but generally remain antagonists?

Eg they are not “protagonist villains” like Walter White, and they are not “redeemed villains” because at least in some ways, they fail to redeem or their growth arc, while present, is stunted.

Usually an antagonist is static, while a protagonist grows to defeat them. But in some fiction, the antagonist grows and changes and yet still is an antagonist.

Jamie Lannister is an interesting example. He starts off by callously pushing a child out a window. And he goes to war against the protagonists of House Stark.

But then he gets humbled, has his perspective changed, fixes some of his weaknesses and leans more on his strengths, becomes likeable by the audience, finds himself pairing up with the protagonists more, etc. So he goes through a growth arc.

But then at the end, he still chooses his original side. More mature, but still ultimately bound by his same weaknesses. An interesting arc to watch, and one that probably would have been more interesting if the last season wasn’t rushed and bad.

Any other good examples? Maybe ones that remain more villainous than Jaime?
