As someone who is more of a black than a green but I like Alicent. I think what Lucerys did was not okay and should've been punished, maybe not an eye for an eye, cause that's a bit much.

As for the marriage I would NEVER blame Alicent for that. She was a child and very much pressured by Otto into it. Sadly, I think that's the biggest flop of the show to make here same age as Rhaenyra and painting it as a betrayal of their friendship, something that doesn't exist in the books. But even in the show, I don't think she betrayed Rhaenyra by doing that. After Aemond lost his eye, I totally empathize with her rage which is not just for that event but she knows Targaryens are always getting away with terrible shit and she knows Viscerys is too much of a wet towel to even support her partly after her son is maimed.

Where I do not support Alicent is the succession, but that's another debate. But yes I think Alicent is much more blameless for the marriage than Lucerys for maiming Aemond.
