Our Sages instructed us to be truly humble before every other human being. And that means having humility even towards someone who is on the lowest spiritual level. Can a great person be truly humble before an evildoer? Yes: By taking the Sages' advice not to judge another until you have come to his place. A person must consider the physical place of the evildoer, as well as his spiritual "place," his incessant, burning passions. And while you can not judge the sinful person, in no way does this justify his behavior. He should have used his mind to control his passions for fear of Hashem. And here's another thing to consider: If you look deeply, you will come to realize that you have a lot in common with the careless person.
