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.
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.
Not to the Kerchers. It doesn't seem that way to them at all. As far as they are concerned, Amanda Knox killed Meredith. And they have evidence and multiple court rulings that agree with them.
There's a slight issue here in that I changed my wording slightly after I posted the comment so that I referred to the Kerchers and their desires. I think that this is a fair response since the subject of your verb is "wanting". I don't think you are appreciating the epistemological issue here. They believe, quite sincerely that Amanda Knox is guilty. They are almost certainly wrong in that belief. But they don't have a desire to harm a random person.
How much of that stupidity is willful and how much is just deep cognitive issues that would ensnare almost any human? This isn't akin to Joseph Priestly trying desperately to think of any hypothesis he could to defend phlogiston becuase that's his preferred hypothesis.
There may be a communication issue here in that your sentence starting "wanting" seemed to be the main jumping off point of my comment. I interpreted that as referring to the desire not any relevant act, since well, wanting is an emotional state.
