In the 18th century English novel, Tom Jones, Henry Fielding concludes the story by saying that ingratitude is the worst sin one can commit in this life. Fielding puts that on the antagonist of the book. That kind of stuck with me over the years. We all sin against each other, so anytime an individual or group of people tries to make up for their sins somehow, only to be rebuffed by the aggrieved party, yeah, maybe ingratitude is the worst sin one can commit in this life. I mean, murder is definitely up there, but maybe he has a point. Maybe Fielding was just talking about the everyday sins most of us are likely to, at some point, commit towards one another in this life.
