A kind of justice that hasn't ben particularly just in the past, which is why vigilante justice isn't legal. The point is to not have citizens deciding to carry out their own idea of justice. That's for the state, which in a democratic society, we vote on, they pass laws which judges interpret and so on.
Because we can't trust everyone to deal out their own idea of justice without it turning into endless blood feuds and partisan killings. Not to mention all the lynchings and witch hunts. This doesn't even bring up the fact that most individuals don't have the resources or motivation to carry out a proper independent investigation. So then the wrong person gets hung by an angry mob, or beat to death by a family member of the victim.
Brian Thompson was CEO for all of 3 and a half years. He was also only about 50 years old, I don't think he's quite the bond villain you want him to be.
I don't follow your reasoning, 3 years is a significant time. Are you saying that you need to be above 70 to become a "bond villain", haven't seen that movie.
But in any case he was working for United since 2004, according to Wikipedia.
It's because they believe in justice that they are celebrating the murder.
