You say “a CEO” like it’s just a fungible human unit. In reality, a CEO is much much more valuable than a median human. Think of how many shareholders are impacted, many little old grey haired grannies, dependent on their investments for food, shelter and medical expenses. When you think of the fuller context, surely you see how sociopathic it is to shrug at the killing of a CEO, let alone a CEO of a major corporation. Or maybe sociopathy is the norm these days, for the heavily online guys.
CEOs are not special humans. They know lots of people, but that's not an unusual trait.
When one gets fired, quits, retires, or dies, you get a new one. Pretty fungible, honestly.
But yeah, shooting people is a bad decision in almost all cases.
The CEO literally is a fungible human unit. Any job can be learned.
