The problem is that it is systemic, the CEO is just part of it, killing the CEO will just cause a new CEO to be appointed, maybe one who is even worse. If it becomes common for unpopular CEOs to get killed, this will select for CEOs who don't mind risking their life if the pay is worth it, essentially the profile of a crime lord. Killing the system is much harder. If you want to go the murderous route, the idea would be to murder random shareholders, not necessarily the CEO, based on how much share they have. It may include the CEO, directors, or maybe you if that company is part of of your portfolio, directly or not. The most effective way may actually be the most boring and frustrating: financial sanctions or outcompetition by a government elected by people who actually care. A systemic solution for a systemic problem. Society has no shortage of nihilistic parasites, in fact normal people can act like this in the right circumstances. And by normal people I literally mean you and me. The problem is addressed by avoiding such circumstances.
