I say this in the nicest way possible, but there is not a single redeeming quality to Jack I can think of, and I can think of one for just about every cow here.
Jack has yet to show a single, genuine, act of kindness that hasn't been motivated by self-interest, narcissism, or a saccarrine sense of sanctimony. He even puts his own interests over those of his children and Tammy.
The only contribution he'll give anyone is a fat life insurance check for his bloated corpse. He is a soulless, selfish, uncurious, entitled, boring waste of air, and he doesn't have much time left on Earth to turn that around.
Whoever has to write Jack's eulogy is going to have a hell of a time saying anything of genuine substance.
