Madeleine L'engle said this quote

If I do wrong, I may do it unwittingly, thinking I am doing something for the best; but if it turns out to be wrong, I have done it, and I must bear the responsibility. It is not somebody else’s or something else’s fault. If it is I am less than human. Like everybody else, I tend to rationalize and alibi, before I let myself admit, “Yes, I did this. I am sorry. I will do what I can to make reparation.” Our sins defeat us unless we are willing to recognize them, confess them, and become healed and whole and holy—not qualified, mind you; just holy.
