I work in a rest home where most employees have some degree of sociopathy (including myself), mostly because anyone who doesn't can't handle making friends with people who die, or slip into senility, or get kicked out because their kids stop paying their bills every month. Being able to emotionally distance myself while still caring for people is a valuable skill. (And the reason I like Lirin so much as a character.)
