It should be pretty obvious that if being a general asshole in a society that awards you for doing so and punishes people for retribution can get you killed, then the same is true if not more likely in AnCapistan. People don't want to share their community with a child murderer, and it's pretty obvious if someone did it on accident (say, firing a warning shot at the kid who keeps trespassing on a nightly basis and accidentally hitting him because you're retarded with a gun) or if they were a faggot and did it intentionally. Even if they did it intentionally, there'd probably be attempts to rehabilitate the town bully/get him to atone for his crimes before people would resort to physical action because he clearly didn't give a shit about social conventions, and there would very likely be no one who'd try to stop said individual/who'd rat out said individual if they took action into their own hands in AnCapistan. There's proportional response, there's justified disproportional response, and then there's taking things too far. Shooting a kid because you thought he was a tresppasser with a handgun when he graffiti'd your house at 2AM is disproportional but could probably be justified as "you didn't know" but shooting a kid in broad daylight because he happened to step on your lawn is a quick way to get yourself killed by a neighbor who's tired of your bullshit. We should also keep perfect crimes out of this whole mess because who cares if you commit the perfect crime?
tl;dr- Principles are applied in ideal situations, and we must assume that the nature of the game changes when actors don't follow the rules or try to use them in their favor. A free society is not restricted by laws that prevent retribution/vigilante justice against such parasitic or misanthropic behavior the way an enslaved society is restricted.
