I do not suggest that life is always fair; but instilling the grievance mentality, as a tactic, has seldom been a way to what is fairer. It has usually been to a quite different purpose, with very little benefit to the person being conditioned.
The Garden thang sure was a sockdollager example of this. Oh, God hates you because He hasn’t spilled all His beans about good and evil to you. Well guess what, you’d never have room for all the beans you’d need, if you had to store them all yourself. So God’s generosity was made to look like some kind of evil plot.
Looking for how a misfortune situation can be turned to one’s legitimate gain works a lot better than the eternal kvetch, that’s for sure.
