Y'know, I've thought a few times in the recent past, that the elites in our courts decide to try and rehabilitate maniacs like this. When in saner times, if courts wouldn't do so, the people would rise up as a mob and take out someone like this, so they'd never have had the opportunity to kill again.

There is so much crime and cultural destruction that goes unpunished now, that as a society, when we were a more unified and moral people, we simply would not have tolerated.
More than that, our society increasingly rewards and coddles bad behavior, and punishes good and moral behavior. That seems to be the guiding principle of liberalism.
