Voldemort was not a happy man. He was far from being happy, in fact. As a child, he lived the life of an orphan, murdering people (just cause he could) as a hobby.
This, of course, led to his loneliness and that – of course- to his pet killer rabbit. Named Snuggles.
But no one knew that.
Just like they didn't know how he wanted his middle name to be Chelsea.
Or how he wished he could be a Drag Queen.
Or how he wanted long, flowing blonde hair like Lucius'.
ALL HE WANTED WAS TO FEEL PRETTY!
But no one would give him that.
And look what that led to:
http/ cheesy smile (though his teeth are nicer than Snape's); a bald, scaly, head; and a nose that lets you know he's been in the meth business for far too long.
Poor, poor, moldy Voldy.
