apologize for a bad witness that was not my own?

The case in point:

A salesman came into my shop one day with the last name of Levine. I guided the conversation to ask whether he regarded Jesus to be the messiah. He told me this story: "When I was a boy some Mexican Catholic boys would surround me and say "You Jewisha? Huh? You Jewisha? Huh?" They would take my Hamsa necklace and **** it and say "What is this? A whistle, Jewisha?"" He went on to say they would continue to taunt him and spit on him and laugh. The look on his was as if he was reliving it right then. If that is what Jesus does for people why would I want anything to do with it? I was moved by comp***ion to apologize to him for their actions and did so.

In your opinion was I right or was I wrong?
