I think, generally speaking, there are very few people who would consider Martin Luther King Jr., George Washington, etc. as "untrustworthy." Some historians suggest that "Honest Abe Lincoln" cheated on his wife with two men.
What could trustworthy mean if historical archetypes of honesty and great morality are not considered trustworthy?
> What could trustworthy mean if historical archetypes of honesty and great morality are not considered trustworthy?
What do the two concepts have in common at all?
Trustworthy means he will not screw me over if, say, I were to borrow him money. That simply has nothing to do with "who the person" is but only with "what he is like in his personal relationships". Business relationships are very personal and greatly dependent on one's personality.
In fact, the "greater" the person (in those historical, societal senses of the word) I'd actually be biased to trust them less even without any knowledge of their otherwise untrustiness.
People can have a net positive on the world and still regularly backstab acquaintances. See Steve Jobs.
