Ah yes, vigilantism from the perspective of the murderer. 'But he was an asshole!' says the person who murdered them. Let's all take the story at face value and applaud the lack of due process and human rights. After all, they were scum (according to the murderer).
For any modern day (western society, anyway) examples you have a really good point, but keep in mind for women in the recent past there would realistically not be any “due process” if they even managed to get an abuser into a courtroom.
“I hunted this guy down and killed him cuz he was an asshole” is very different from “I had no way to escape this guy and I did what I had to to get away”. The fact that these women had to resort to murder to get away from their abusers is disgusting, but until/unless I live thru a situation like theirs I’ll personally save my judgement for the system that put them in that position rather than the women themselves.
My point is we’ll never know if these people were actually abusive. I’m not saying murder is never morally justified, but simply assuming the murderer is in the right because they said so is certifiably nuts.
I get what you mean - in any particular case it might not be possible to ever prove that the murder was actually morally justified, so maybe we’re just giving some batshit crazy stab-happy lady a pass for no reason. Still, even if we can’t know whether or not it was morally justified, we can and do know that the conditions that would justify it were common enough that I’m personally comfortable with the odds ¯\_(ツ)_/¯
Don't try to talk sense into ppl online. Most of them are already lost causes and just like hearing about stories that confirm their biases. Spend your time and energy in the real world where ppl are somewhat normal and have a good head on their shoulders.
