This is exactly where the justice system came from.
Everybody died earlier back in the day; there wasn't enough iodine in our diets and everybody was generally pretty slow.
One day, someone lost their shit and killed somebody or stole their shit. Everybody was like, "What the hell Chad? Why did you do that?" Chad was all like, "sorry..." and they were like, "ARE YOU FUCKING SORRY?" So they stood around and spit and wiped the shit off their pants and wondered what to do.
Somebody was like, "Let's put him in a cage and shit! Or should we hang him?" People were like, "You know what, how many think we should hang him and how many think we should put him in a cage?" People raised their hands and spit and thought deep thoughts and shit. They were all about 17. Eventually, they decided to just beat the shit out of him, and so the justice system was born.
Chads everywhere knew that if they stole/killed, they would get their ass beat, and since they didn't want an ass beating, they decided not to steal/kill. Things were pretty good, a couple Chads fucked up as Chads do, and they got their ass beat, but eventually some of the Chads just kept getting better and doing the same shit, and the ass beatings weren't enough. Eventually they got tired of beating his ass, so they locked him up in a cage and forgot about him for awhile. After a bit, Chad was like, please let me out ... I won't do it again, I've learned my lesson, and so it was.
Eventually, one Chad was such a bitch that he just kept doing shit over and over every time they let him out ... and it got so bad that he finally killed someone while trying to run away, so they had had enough of Chad. They shot him in the face, and they didn't have to worry about that Chad anymore.
Nowadays, we can't even kill somebody by shooting them in the head, because we are "more advanced." We come up with some crazy machines that put them to sleep first because we are "civilized." It's a fucking joke. It doesn't matter how you do it, you are killing someone.
You can make it seem more humane, but it's laughable when you think about it. There is nothing "humane" about killing someone. We do it, most of the time, because they have killed someone else, or harmed someone else in such a horrible fashion. The thing that doesn't change, is the problem: Chad. We need a solution for Chad, and some Chads just won't learn; it's a fact of life. Some Chads will make their way in and out of jail; some Chads will learn, and some won't. If a Chad fucks up enough, he will be left in a cage until he dies or is killed.
It isn't complicated; it's as close to justice as we can get in our own lives.
We shouldn't have to spend our lives dealing with Chad.
