Canonically - sometimes werewolf transformations just go wrong and you end up taking the shape that reflects your personality.

All of that "orphan" stuff may have played into Jackson's personality but it didn't determine the shape.

In other words, orphan status is not pre-requisite for becoming a kanima.
