This is my position. Just kill them and move on, we need to make humanity better. There are people who need rescue and care.
Mind, we should keep monsters like Maxwell alive for awhile...so that we can get information about where the innocent have been trafficked. One entire year for all the actionable information that Maxwell and company are willing to trade. No bargaining, nor exceptions, just a delayed execution after the plea deal is struck. Without the deal, immediate execution after a brief trial.
...I am hoping that there are enough little black books, that delayed justice isn't needed to save the innocent.
