Cannot speak for Itaewon Class since didn't bother watching it but one thing I know for sure is that you believe everyone with ASPD to have severe ASPD with no exceptions. "They cannot fall in love, this is a romanticisation." Every mental disorder lies on a spectrum. ASPD is no different. KMY had ASPD as well as PTSD and that coupled with the fact that everyone around her always painted her out to be a villain had made it worse. Even as a child she believed herself to be a villain. The most common symptoms in ASPD are in fact, disregard of the law, not acknowledging own faults, disregarding possible consequences of their actions no matter how serious. This is was shown very well. With time and help, proper therapy and support, a person with ASPD can differentiate their emotions, how people perceive them and also learn their own faults. These are all steps to slight recovery. Not everyone with ASPD must be a full-fledged psychopath or not have anyone fall in love with them.

Gang Tae believed that his sole purpose of existing was that he must take care of Sang Tae and felt guilty for not doing that sooner. Sang Tae on the other hand was aware of his turmoil and blamed himself for not being able to take on the role of a big brother like people normally do. Ultimately, Sang Tae learns that he doesn't need to be as normal as possible to be a big brother to Gang Tae and he is not in fact a burden to Gang Tae. And Gang Tae learns of how Sang Tae has always tried his best to be a big brother to him and realised how much Sang Tae's existence is necessary to him apart from being his only alive family. This was the entire point of the title - "It's Okay To Not Be Okay." implying that it was in fact not necessary to have lived an easy life, to have never done something you forever felt guilt for or for you to not be mentally ill to be considered "Okay."
