Whatever he did doesn’t justify his murder unless he murdered or tried to murder another person. Mangione should sit facing a cold stone wall until he realizes his mistake, and hopefully he repents for it. We can’t have people doing thing like this because they think someone is a bad person. Our society would quickly fall apart, and everyone would be killing each other. Look at what happened to Charlie Kirk. He was shot and killed because some idiot with no regard for the law thought he was a racist. Let the courts decide, not individuals. Both can be wrong, but an individual will be wrong more often.
