Hahaha - Sorry, but of course the "tragic" one is the one you like best! You know how much I heart you, right? 'Cause I totally do!
I've always felt for Severus. Rowling gave him such a craptastic existence, with limited redemption. Makes you wonder, in canon not fanon, what Sev was thinking when he pulled Harry so close to him. faeryqueen wrote a story once about what might have been, that he hated Harry for not being his son, and I have always LOVED it.
