A reason to bleed?

"There is nothing more crucial to existentialism than the belief that we can know only what we live: we know we are free because we experience our own freedom in anguish. We know that we fear the "sticky death of the For-itself in the In-itself" because we know, or are open to persuasion, that vicious things horrify and fascinate us... For Sartre... it was of no use to tell people that something was true; they had to feel that it was so, and accept it for themselves."
