A person who is confident in the use of his/her
can lie - or kill - and will not care if someone else says, "you lied and killed, you are a monster" - because said person will "know" that the lies and killing were "justified" - according to this person's own subjective criteria, of course, but that it is precisely what
is about.
Another person who has less confidence in his/her
could do the same but be shaken if someone calls him/her a monster, thinking, "uh, maybe what I did was wrong, now I'm not sure, damn, why can't I ever be sure about such things?"
