Be enthralled in the difference of peoples point of views. cruelty can often be traced back to a difference of opinion. Our ability to think such different things is one of the many beauties of mankind. Acknowledging this might “set you free.”
Ex: the crusades can be seen as a case of a difference of opinion. Europeans thought the holy land belonged to them and wanted to take control of it. So they went to war and performed cruel acts against the people already residing in Jerusalem, following their religion. Those already in Jerusalem might have felt differently.
