Again, I'm telling you all that being antisocial and having Antisocial Personality Disorder are two VERY different things. People with APD are the murderers, rapists, and thieves of the real world. Being antisocial is just being a person who selectively avoids socializing. Having APD is being somebody who has:
- a disregard for the most basic rights of others (sees them as a tool)
- childhood history of aggression
- inability to empathize
- lack of guilt or remorse
- chronic lying, manipulative, charming
- irritable
- reckless
This can often include having a narcissistic view of self and lack of sociability.
I get that one, although I am not firmly convinced that Xehanort totally falls into the schema, as he seems to
choose not to socialize instead of being
incapable of it because of a mental illness. The latter would also throw up the question if an insanity defense could be made on his case, while the former would just reveal him as a huge self-centered douchebag.
Going by the seven bullet points above (seven, is that intentional? Lol), the first definitely applies to Xehanort, as do the points three, four and five.
Point two cannot really be verified since we didn't see Xehanort's interactions with others during childhood. Young Xehanort in DDD though seems to be calm and collected most of the time, only getting really aggressive when "present"-Xehanort possesses him to fight Riku.
Irritable and reckless also don't apply to him, as he's rather the opposite in nine out of ten cases.
Nonetheless, reading up on the issue I would not rule out that Xehanort has contracted a variation of APD since his heinous actions surely cannot be excused with well-intentioned extremism.
But he still called eraqus brother. That has to have some sort of meaning. Its not out of the question for both of them to have been close while they were younger, but grow apart due to conflicting ideas as they got older
Monks of the same monastery also call each other brother every day, that doesn't mean they are also close in private. It may be not out of the question, but the hints and indicators shown throughout the reports, how callously he decribes the relationship which he abandoned at once when his curiosity took over again and the general distanced behaviour of Young Xehanort point strongly otherwise.
Combining that with the proposal Spockanort made about a probable mental deficit on Xehanort's side make this even more likely. Even the so often cited "moment of mercy" Xehanort
supposedly had towards Ventus can be de-constructed easily by keeping in mind that
he himself was solely and utterly responsible for the kids' horrible state in the first place, which was neither an accident nor done with good intentions but just to fuel his own desires and plans. The tool had no use anymore so it could be dumped on his own, equally much disregarded homeworld.
People, hearts, even
worlds mean nothing to Xehanort at all as long as they don't have some use in satisfying his curiosity or can be used to further his plans.
Unlike Sora, who has proven by now that he cares greatly for Roxas who was created from him, I doubt Xehanort even feels something for Ansem and Xemnas at all, they're just more tools.
I think it would be interesting if Xehanort achieves partial victory in reuniting the worlds through Kingdom Hearts, but is stopped short of destroying all life and changing the ballence of light and darkness. This would create an opportunity to create an entirely new status quo for the KH universe and would give Xehanort's actions permanent significance in future installments. Even though he is out of the picture, we will know he is to blame for the way things are in this new saga. It's also a chance to completly retool the way the series works from both a gameplay and story telling perspective.
Disney won't allow that. One of the principal rules Disney set on start of the KH series was that Disney main movie-characters had to remain confined to their own worlds, which is why we only see some limited characters as summons outside their own worlds. So putting all the Disney worlds together into one probably won't work.
I'm also on the fence of giving Xehanort even more credibility/legacy. Many people seem to finally want to get rid of the monster and the new saga having as little as possible to do with him.
It also stands to reason that each ending of a KH game so far already included a partial victory for Xehanort or at least not a severe setback, so another interesting twist would probably be that when implementing his final master plan Xehanort actually gets utterly defeated and for once accomplishes completely
nothing.
I would even go so far and propose that the X-blade should never be truly forged. He can fabricate and ensure the clash happens, but each of the seven lights could(and should) actually refuse to have their hearts a part of it and so even if the ugly thing comes into existence it would be so brittle and useless that the lights destroy it the moment it emerges, giving Xehanort a massive middlefinger before saving Terra(if that hasn't been archieved already) and proceed to blast Xehanort and his remaining darknesses to smithereens.
