So Aaron was always a little messed up in the head since the first chapter. He was just really good at masking it. At the end of season 2 Yujin left which made him lose his cool. In the process of finding Yujin, Aaron seems to have gotten more unhinged and desperate. After finding Yujin(Yujin you and that stupid stubborn mouth of yours is going to end you) and hearing Yujin just bait him Aaron seems to have lost it a little.
Note: I’ve seen people say in this that this is non-con. Which it isn’t. Yujin purposefully baited Aaron like that. But they also aren’t entirely wrong that this might be going into darker territory as Aaron Hunter is possessive as hell.
