The Kanima's Beastiary entry:

“Like the wolf, its power is greatest at the moon’s peak. Like the wolf, the Kanima is a social creature but where the wolf seeks a pack the Kanima seeks a master. The Kanima, a weapon of vengeance, is used to carry out the bidding of its master. The Kanima was once used by a South American priest who took it upon himself to rid his village of all murderers. The bond between master and servant grew stronger until the will of the master became that of the Kanima's and whomever the priest deemed unworthy, the Kanima served his vengeance. The Kanima is a mutation of the werewolf gene that cannot fully transform until it resolves that in its past which manifest it.”

Jackson's inner turmoil caused him to reject Derek's bite and the Kanima was a direct reflection of his emotional issues.
