To depart from evil is understanding (Job 28:28).
Sin is something altogether mysterious and awful: a turning away from God and a turning to the changeable good. As broken human persons, we create for ourselves a myriad of excuses for the sins we commit. It seems that our changeable and too easily distracted mind can hardly conceive of the idea of the Supreme Good (God) and still less hold It as the object of its preference over and above all else. In every sin, therefore, there is some element of error, a mistaken judgment.
