It is said in the name of the famous Kotzker Rebbe zt”l, that everything in this world has a purpose, even "קרומער שכל" - distorted logic. It is meant to be used with a vivid imagination to figure out a way to get people off the hook and judge them favorably, to be דן לכף זכות. Says R’ Zalman Guttman shlit’a, on the holy day of Rosh Hashana, there is probably nothing more important than applying this midah. We must remember that Hashem works ‘midah k’neged midah’ measure for measure. 

     Thus, if one will ‘sit in judgment’ and look down on others, Hashem will sit on His Throne of Judgment looking carefully and even harshly at him. However, if one looks away from people’s faults and focuses only on the positive, Hashem will do the exact same thing for him! 

     So here’s a bit of ‘legal’ advice: Be smart and ‘hire’ Hashem as your attorney for the Yom Hadin - by judging others favorably!”
