How to break a spiritual contract made discarnately? (if possible)

[Cannon]

When I finally reveal, through finite poetry of infinite subtlety, my suffering, that was for you without the expectation of recompense, you will demand to give me recompense.

For it was so powerful it caused negatives to go positive, and positives to go negative, but I kept the Faith and remained the serviceman, the Sergeant with the Cannon.

So in return I will ask for: "Oblivion."

And so grateful will you be at my service, that at first you will think, astonishingly, he wishes to die!
