Jack has no interest in sacrificing anything. Just look for whatever diet bias lets him keep eating cheese and meat.
Though true, it’s still too generous: Jack is desperate to qualify eating himself to death as somehow being
the morally correct position on the Earth to qualify and entitle him to talk down to others from (all while peering up at them from his toilet on wheels, and forgetting how to speak).
These window dressings framing his consumption of fad diets [cheating], reviewing of fast food service [abusing the staff], espousing the health benefits of his personal brand of slow suicide [attempting to mislead others to follow his example, in a prescriptive manner devoid of either ethical consideration or even insight], etc. are secondary pretensions to his only
real priority of rationalizing the defining hedonism and tragic absence of impulse control which have relegated and confined him to the scootypuff throne upon which he embodies the cardinal sin of gluttony. Denial compels Jack to avert his working eye away from his own mortifying reflection as he insists that he is
ackchully Living His Best Life while he waits to ascend to his rightful place at Geesusz’ side at the Big Buffet in the Sky...
...Even though heaven can’t be heaven for anyone else if Jack is there to shove past everyone in line while honking his scooter horn, demand the angels wipe his ass, or sit in Gawd’s seat at the heavenly table while he complains about how Librulz have been ruining heaven ever since he arrived.
The truth which even Jack knows is that he is eating as much as humanly possible as a means of raging against the dying light in the only way he knows to, perpetually seething in the knowledge that he can’t take any of his gud meats with him, where his ignited fat will burn as the brightest candle in hell. Jack has done more to desecrate the temple of the body that even Ellen Page; and his only chance of being somebody in either this life or the next is in being promoted to being some corpulent, front line demon for Spawn or somebody to easily dismember.
The single greatest irony concerning the thorough fraudulence with which Jack has adopted “kermivurr” as his personality is that he is both a fruit and a vegetable.
