Taken to its logical conclusion, one could follow anyone around and claim they aren't doing the most right thing. The "right thing to do" is a scale, not binary, and it often conflicts. E.g. right thing to do for self health, vs environment, vs for my customers, vs for my employees, vs for my family (and time with them), vs happiness (for self and others), etc. GP is right, you have to align "right thing to do" with "prudent thing to do" and it becomes viable. Otherwise, to many it comes off as preaching as though they are bad people when they only optimize for other right things.
