It still says something about the author of that character, that they (a) went through the effort of writing that reply and (b) there is not a single reply in the empathic/non-sociopathic direction demonstrating an equal amount of effort. I don't really see the relevance of it being a role-playing character at all - it's hardly incompatible that it's both a RP character and a sociopath who has chosen a sane cover for posting their socially unacceptable views (after all, Voldemort has all of 28 karma; he clearly gets down voted a decent amount)

The simple Bayesian evidence is that someone cared enough to write a sociopathic reply that was fairly in depth, and the only non-sociopathic replies were a link to a webcomic and personal preferences of "well, yeah, I'd pick immortality over 28 lives..."

Also, lumping Clippy in with clearly fictional characters is just rude ;)
