As someone with a psych background, I wouldn't say it's impossible but it's more likely that he just has severe PTSD. Growing up in a traumatic environment can and will warp you in a lot of ways. PTSD manifests in different ways in every person, simply because every person is different. For some people, it may manifest as rage, which is exactly how it seems to have come into existence for Eunyung. He may be neurodivergent, but it's also highly likely that his parents are just victim-blaming, as is very common for abusers to do. Hearing "it was hard for me too" is common for victims, but that statement often omits the fact that causing trauma to people tends to make them more difficult... It's a bit of a vicious cycle.
I feel like Eunyung might suffer from BPD considering all that’s happened in the series, what really confirmed it was how his parents had said he’d been hard too raise and his own realization that he’s always been this way, even as a child
