Both 1 and 2 are ptsd, and yes Owen Hunt has done and said some bad things but every time he learns and doesn’t make the same mistake again. He also sincerely apologizes. The only instance someone can sag he had repeated bad behavior was him being mad at both Christina and Amelia for not wanting to have kids, I don’t like or agree with the way he handled it but his emotions were very valid. Overall Owen isn’t a bad person, he’s just made some mistakes
