Ultimately I do believe in rehabilitation, that being said I do think there’s a limit to medical science. Since Invincible is a comic book with far more fantastic ideas than advanced medicine, I’ll suspend my disbelief that they would have the means to cure sociopathy or psychopathy, but in the real world I am of the opinion that only someone irreparably broken and sick would be capable of doing what Sinclair did, and the only real solution is for them to be removed from the public for the safety of others and also themselves.
