Remember the seven cardinal sins? You’re given the serious task of adding a new one to the list — another trait or behavior you find particularly unacceptable, for whatever reason. What’s sin #8 for you? Why?
I would probably say stubbornness, though admittedly that does relate to pride in a way. I guess most of the behaviour I dislike can be connected to the seven deadly sins; indifference is loosely tide to pride as is arrogance.
Exploitation, willful exploitation I guess would be the eight sin for.
