[Beetlejuice]

Do people not realize that honesty without honor, integrity, wisdom, fairness, kindness, justice, responsibility and temperance is worth very little? Some of the most repugnant human beings in the history of the world have nevertheless been "honest". So what? Who cares? It doesn't tell us anything important about who you really are.

And in the case of Helen, she isn't even honest anyway. She sure as hell isn't honest with herself. And when people try to be honest with her she just talks over them to block it out. When she's given warnings she accepts them, but only because she has to. Not because she's honest enough to admit she's done wrong.
