I mean why does he let the company blackmail him? he could go to jail for a few years instead of screwing up lives of people he cares about. also, what exactly is his job? what does he do all day (except from watching beth/sarah obvs).
also, in the first episode, he sleeps with sarah event though he seems to realize it's not beth and she wants to distract him.
i just can't get a real opinion on him (but maybe, i guess, that's the point. all characters are flawed which makes them seem more realistic)
