Once he has done so, he can guarantee that the sin will never recur. Let us now explain. The Rambam enumerates twenty four obstacles to repentance. Certain actions reflect an attachment from which man is not easily weaned. Let us analyze the scales of judgment.
Every human being has merits and sins.
He whose merits outnumber his sins is a Tzaddik, and he whose sins outnumber his merits is a Rasha. Half and half is a 'Beinoni'. This measure is not according to the number of merits and sins, but according to their weight. And so too, the entire world is half meritorious and half guilty. If he sins one time, he will tip his scale, and all the world's, to the side of guilt, causing destruction.
