I think the argument between who's the worst of the world leaders is silly. They all suck. Using chemical weapons on your own people is wrong. So is enforcing a system that subordinates women. So is stealing the resources of the populace to self-aggrandize. At this point, Assad and Un are not rumored to buy a major football clubs, MbS is.
Comparing a leader to a corporation is also silly. Trying to quantify how many people a corporation has killed seems like a foolish task and one that is fraught with difficulty to the point of impossibility. It's much easier with regards to leaders of countries. Regardless, once again, we're stuck with the unassailable fact that Chevrolet does not own a major football team.
Now, there are some highly questionable owners in terms of business practices. Many owners fit this description. However, looking at the harms of certain business practices differs, at least to me, from looking at the actions of dictators and the like. I am fine with saying that it's worse to, say, order the bombing of people than to provide less than a living wage (albeit a legal wage) or to cause pollution.
