I am a bit in the middle about Damien. Right now with the information we have been given so far, I'm leaning towards "Three strikes, you are out". But I also have to take into account that BD likes to tease us by only giving us tidbits of information at a time. He obviously has more planned for Damien, but it's still up in the air if it's going to be a redeption arc (hopefully optional) or a further descent into outright villainy.
In my opinion, Damien's character arc is more complex and thus more interesting than that of the rather one dimensional Ryker. To use an MCU analogy: Ryker does things strictly for self-gain, for profit and out of a near pathological dislike for the MC, so he's kinda like Yellow Jacket.
Damien does bad things but seemingly with more altruistic motivations: to protect his family. In that way, he is more similar to MC than to Ryker. MC would also do anything to protect his family (and not all of them are nice, as Ryker can attest to). Similar motivations, different methods to achieve their goals. Kinda makes Damien the Killmonger to MC's Black Panther.
In short, while he is in the danger zone, he hasn't crossed the Moral Event Horizon just yet IMO, and I'm interested to see where it all leads.
