Unfortunately, they are people. Evil, narcissistic, sociopathic, detestable people. Dehumanizing them is easy because of how inhumane they are, but it jumpstarts one of the more verified slippery slopes that ends up "justifying" atrocities.
That being said, I'm all for them being stripped of every possession and asset they've ever had, sending every participant family member and associate put in a different high security prison for life, and possibly sentencing them under 13th amendment slavery rules with all revenue going to addiction treatment.
Because they're people. And they deserve all of the things our judicial system has to offer. As people. Evil, shitty, greedy, people.
