I wouldn't say he's a bad guy. After all he was doing his job that he was called for and it's not his fault they didn't put him back. He also completed his half of his deal with Lydia, and she didn't complete hers (not entirely her fault, so we're willing to forgive). Is he meant to be an antagonist? Yes. It he a bad guy? Nah.
Anyways I love them both equally.
