Destroying the soul pact was not as difficult as Jason expected it to be and was quite easily done.
After he had overwhelmed Ben's soul, and become his soulbond contractor, the enslavement soul pact lost some of its potency.
This prevented Tom, who had become Ben's master owing to the enslavement soul pact's regulations, to order Ben to kill himself, or Jason.
Even though that was interesting, it was more important for Jason to figure out the exact procedure of destroying an enslavement soul pact.
Thus, Jason used his Emperor Eyes to perceive everything about Ben, his new soulbond's soul and state.
A few minutes passed and it was only then that Jason started moving. Using the soul connection he and Ben had, Jason transferred some of his aura to Ben in order to envelop the imprint on his youngest soulbond's soul.
This imprint was in fact the enslavement soul pact.
