Protect Peoples' Honor
The most important foundation of Torah living is to honor and respect the Creator of the universe. When you fulfill His commands, you are actively demonstrating honor for Him.
This is why Judaism considers humiliating another person a most serious crime. When you embarrass someone, you are doing much more than just causing pain. You are attacking his dignity. Recognizing the dignity of human beings is part and parcel of the honor and respect one owes to the Almighty.
When you understand this properly, your every encounter will be based on this inner respect. You will treat each human being with the respect of royalty. As Ben Azai says in the Talmud (Yerushalmi Nedorim 9:4): "'When G-d created man, He created him in His image' (Genesis 5:1) is the most important principle in the Torah."
Today, resolve that if you ever see someone trying to humiliate another person, you will speak up. You might say, "This person is special. Please be careful with his dignity."
