In my opinion this is written beautifully. There’s a big difference between choosing violence mournfully and not choosing violence at all. I can see the killing of a human being - even if it is a murderer - as wrong and sad and mourn the loss of a person, while simultaneously acknowledging the immense (in a way positive) effect this had on the people, its grotesque sparking of hope, and the cruelty of the victim’s actions before their murder. Both things can be true at the same time.

There’s also a difference between being found guilty and being sentenced. I personally would not have a problem with the murderer being found guilty. I might be awkwardly relieved if his sentence was nullified - one day less of life in prison for every person’s death the CEO has (more or less indirectly) caused. He would not have to serve one day after the verdict. Probably, though, there will be harsh sentencing, I doubt that the murderer didn’t expect this. I think he very well understood that his actions would have personal consequences, but that there is a big chance that his actions would also spark something incredible for society and he must have been willing to pay the price.
