Doing nothing is as guilty as taking part?

In high school I remember walking through campus and hearing laughter and people cheering, then I saw the joke. 6 guys holding one up crowdsurf style lifted into the air completely naked struggling, begging them to let him down and everyone else singing happy birthday. They paraded him with everything on display spread eagle and everyone just laughed and sang along. As he was carried past me we made eye contact, I saw the tears in his eyes, I felt his humiliation. And saw him fade away when he realized this was it. Then at the end of the song saw them take aim at the flag pole and heard the dull thud and his scream as he went sack to pole, metal to skin, and they left him there on the floor crying and writhing. It was all chalked up to “kids being kids” but what pains me the most is no one did anything, including me because I knew helping would mean I’d be paraded in the same manner. So I kept my head down
