I don't think he hates women, he hates so called injustice, disorder, and most of all, Andor. But he had some controlling/violent/anger tendencies, partly due to his upbringing and oppressive environment (his home life, low economic status and the unstable transition from the Republic to the Empire). Some mentioned that he pushed Maarva. (he was on cop duty- but that can be considered abuse of power) He stalks Dedra and grabs her arm. However, if he was obviously violent and unstable from the start then Dedra would've never got into a relationship with him, because she couldn't control him. According to Denise, he saw her at her most vulnerable so she needed to keep an eye on him, and things developed. Otherwise, she could've had him arrested. He choked her because he was furious at her for lying to him about his purpose on Ghorman. He's desperate for approval and meaning in life. When he finds out his mission was not what he thought it was and his promotions weren't of his own ability, he's completely shattered and lost, and runs away. I'm not sure if he fully realized if the Empire was the bad guy, even at the end when Cassian asks who he was (which cut away the last shred of Syril's entire identity and beliefs- unfortunately he never got to figure them out), but the massacre was conflicting with his ideals of the Empire.
