While we hear about Bayes' Theorem being under threat in some courts, it is nice to savor the occasional moment of rationality prevailing in the justice system, and of mistakes being corrected.
Congratulations to the Italian court system for successfully saying "Oops!"
Things go wrong in this world quite a bit, as we know. Sometimes it's appropriate to just say "hooray!" when they go right.
Discuss, or celebrate.
I'm curious. Have you ever lost a loved one due to someone else's actions? The closest experience I have to this is a cousin who was killed about a year ago by a speeding driver. My cousin Brandon wasn't that old. He hadn't been a great student in highschool but had really shaped up and become a lot more responsible in college. Brandon was working to become a chef, something he was clearly good at and clearly enjoyed. My cousin was on his bike and never even saw the car. He had on a helmet. It saved his life, for a few days. His grandmother, my aunt, was on an airplane flight when the accident happened. She was on her way to the funeral of another relative who had killed himself. She found out about the accident as her plane taxied to the gate.
At first, after a few days in the hospital it seemed that Brandon was going to make it. Then he took a sudden turn for the worst and his organs started to fail. The end was so sudden that some of my relatives saw in their inboxes the email update saying that Brandon wasn't like to make it right under the email saying he had died.
Then, it turned out that the driver of the car had a history of speeding problems. He received in a year in jail for vehicular homicide. A small compensation for the entire life Brandon had in front of him.
If someone came up to me, and gave me the choice of making that driver die a slow painful, agonizing death I'd probably say yes. It would be wrong. Deeply wrong. But the emotion is that strong; I don't know if I could override it.
But I can still understand that that's wrong. The driver was an aging Vietnam vet with a history of medical problems. He had little family. He was so distraught over what happened that when initially put in jail before the trial, there was worry that he might kill himself. He seems to be an old, lonely, broken man. Harming him accomplishes little. And yet, despite all that, the desire to see him suffer still burns deeply within me.
How much more would I feel if I thought that someone had killed a relative, or even my own child? And if the court had repeatedly agreed and told me that that was the guilty person. How could I ever emotionally acknowledge that I had been after the wrong person, that not only had I persecuted the wrong person, but the person who had done this terrible deed was still out there, and free? I'd like to believe that I'm a rational person so that I could make that acknowledgment. But the fact that even when it is just a cousin I still deeply desire someone to suffer in ways that help no one at all... I doubt I could do it.
To call the Kerchers evil or their desires evil is a deep failure of empathy.
You're talking about killing that driver. The actual villain in the story. I don't have any particular problem with vengeance, I often advocate it. But that's an entirely different to killing Mortimer Q. Snodgrass, who lives at 128 Ordinary Ln. just because... well... you really want to kill somebody. This isn't even a case of finding a different driver who also happens to be reckless and likely to kill people like your friend. This is choosing to kill someone with a AAA driving rating who you have no reason at all to suspect is dangerous.
Even leaving aside the difference between saying that a behavior resolves as evil and calling a person evil I suggest it is you who is failing at empathy here (partially as a result of the aforementioned simple comprehension error). I am empathizing here with all the victims of blatantly irrational persecution. The lives destroyed because people use their social influence to make their community destroy others because of their own willful stupidity.
If I hear a story of a father going out and killing his daughter's murderer I would shrug, have no particular moral judgement and definitely not call the act evil but still advocate a minor prison sentence purely for pragmatic reasons. But when if that same parent started publicly declaring that somebody should be punished when no evidence supports that theory and he is being entirely stupid then I would call the act evil. Because while the damage done to innocents is amortized (sometimes it outright causes them to be killed, sometimes it does nothing) it is still a massively toxic and dangerous thing on average caused by features of my species that I detest.
