Stallman is also a sociopath by your definition then; remember his comments in some mailing list when someone announced they had had a child. There are plenty of other examples. Richard Stallman is an asshole. A brilliant and useful asshole, but an asocial asshole incapable of basic empathy nonetheless.
I don't admire either of them (though I'd give more credit to Stallman for fighting the good and difficult fight all these years), but it seems to me that Stallman's supporters behave exactly the way they claim Jobs' supporters do - by eulogizing and finding excuses for the ugly sides of their heroes and claiming "the others" are a cult.
History is full of brilliant and useful assholes. both Jobs and Stallman should be given their rightful due and called on their failings. But neither of them should be casting aspersions about the other (not that Jobs can do that anymore). At some level they are fundamentally the same.
I can't find that comment:(
