Nice rant. Too bad reality is different; some people need to be permanely isolated from society. This is the real world, guy.
And, yeah, I zero sympathy for people who delibertly murder kids the way the person in Nashville did. Throw her in an prison/mental hostipal for the criminally insane and throw the key away.
if that conflicts with a well intentioned but hopelessly unrealistic declaration, so be it.
But if we earnestly keep trying to turn these monsters back into humans, we'll eventually figure out how to do it, and then they can go free.
