There are more people who can say “Brian Thompson killed my father”, than there are “Luigi Mangione killed my father.”
Also, what does it have to do with whether he was a father or not? If he had had no kids, would that change anything? Can it be more acceptable to kill someone who hasn’t had kids? What’s the point in that?
I am not at all worried about his kids. His kids are set for life.
I am worried about other kids- and adults- suffering due to a much less discerning and less accurate copycat vigilante. It hasn’t happened so far, but it is something that greatly concerns me.
This assumes the kids didn’t already hate his guts.
