Just because someone is terrible doesn't mean they aren't worthy of sympathy. I imagine it must be terribly difficult to actually be Devi Ever. To live inside your head, with glimpses of what being normal would be like, and the occasional faint echo of conscience trying desperately to remind you not to be a total selfish prick all the time.
Is that effort wasted on her? Yeah, probably, but it's my effort and I'll waste it if I want to. I'd rather try my very best to empathize with the cow and get burned occasionally (and lets be honest, I'd hardly say we got burned here) than to close off the empathy valves and just say fuck em all, let god sort them out.
So no, Mr. LikeicareKF, I will pity her/him/it, because I'd want someone to pity me if I suddenly contracted incurable stupidity.
