I suggest you think about it first. If you "return the favor" to him, will you be honest and what will be the impact? If it will affect the relationship between parents, it should be carefully considered.
Secondly, I hope you can talk openly with your father about it. He is your father's friend, and he should have his own ideas about how to treat people.
Finally, your friend said, do you think this person is a debt of gratitude that you need to invest? Don't think about whether he can help you in the future, think about whether he can destroy you first.
As you know, "vengeance" is not a positive word. Being an upright person has nothing to do with whether others hurt you or not, just do the right thing.
