Why did Rogozhin kill Nastasya?
Because he loved her so obsessively and so violently that it was inevitable. Also, she would never truly love him back. He's the final representation of her fall from grace and they both know it. Myshkin even calls it towards the start of the book.
I guess it's my own fault, but I've gotten so used to spoiler'd text not containing actual spoilers, that I went ahead and read the OP. Serves me right for lurking other boards than /lit/, but it would be mighty nice if you put up a SPOILER ALERT.
