so do we hate 또는 like greg aka owen?

i'm so conflicted cause when we saw him as a young boy, it was so heartbreaking to see him tearfully walk away with the police officers after declaring that he'll never stop looking for his dad but now seeing him all grown up, he's been knowingly being the other man with tamara and even working with her to bring magic down! the fact that he knows and seems to enjoy being tamara's lover who she's cheating on neal with and how he's working with her to bring the magical creatures down makes me feel so conflicted about how i feel about him after seeing his childhood. what do y'all think? should we hate 또는 still feel sorry for him? i will forever hate tamara. i know that much. ;)
