I don't ever want to celebrate someone's death. The fact that we as a species still produce people who's removal from this earth are absolutely worthy of celebrating is gross. The act of celebrating isn't. Don't get me wrong there. But what kind of awful world produces someone who's so awful not only is his murder celebrated pretty much universally and it doesnt even chsnge anything? This is necessary violence but the fact that it is necessary and worth celebrating does illustrate how absolutely fucked and inhumane things are. I hate the ruthlessness I've had to adopt. I hate celebrating death even when I like it. I hope one day every death is an actual tragedy.
You're right but I also don't see a situation in which things would ever change, at least globally. There will always be awful humans, as only so much negative behavior can be mitigated by environment, education, therapy, and improving material conditions. Even the best existing examples of socialism had/have murderers and people who commit other heinous acts. I get what you're saying about the extent of it though, in that those are more isolated incidents born out of a spontaneous action, whereas this CEO and their actions are chronic/ongoing, relatively common and universally hated yet still tolerated.
