Kyp's fall is as rushed as Ulic's was. Ulic had an overabundance of pride, but instead he fell to the dark side because KJA ran out of pages and made him swallow a Sith worm. Kyp has vigor and brashness but instead falls because he gets possessed by Exar Kun. In the next book, he's released from the grip of the dark side not because of his own choices --- but because his fellow students defeat Kun and vanquish Kun's spirit. It's not a tale of a fall and redemption, at all. It's a tale of rushed sloppiness and of actions beyond the character's control.
