I always maintained that humanity has not reached a virtuous level. Aristotle maintained that a virtuous person has ideal character traits. Still, virtue does not come with a step-by-step tutorial on how we should act for lack of clear principles other than “act as a virtuous person would act given the situation.”
furthermore, some people may have a sense of entitlement or a lack of empathy, leading them to behave in a way that, in their mind, justifies their bad deeds.
