The biggest irony? He was the most useless of the crew, caused the accident incident, and got a bunch of the survivors killed. Yet he's one of the people left alive once all the figurative dust settles in the season finale.
If there's a season 2, Kamen will probably get a redemption arc. He came to finally realize HE's the problem. He's toxic. His wife and a majority of the crew died because of his actions. Admitting you're the problem is a good first step.
