People with malleable morals that can be bent to exploit every advantage are not “agile” or “adaptive”; they just plain lack integrity.
Spin can’t change reality. A dishonest act is still a dishonest act regardless of how it is rationalised.
If you found $200 on the street, the right thing to do is to hand it in at the nearest police station. A dishonest person would keep the money and then justify their action: “the police will keep the money for themselves anyway…” etc. And still believe they are fundamentally honest.
