Corporations are executed all the time. Almost every state has a list of corporations that it has dissolved and or prohibited from operating within it's state.
What you seem to be confused on is that you actually think a corporation is somehow sentient. It isn't, it requires people inside the corporation to pull the levers and move the switches that make it run. Those people are the ones who are criminally liable for killing people if you can prove it. If the CEO says, "screw the safety cables, get the whatever online" and then something happens causing the death of 5 people, the CEO and everyone under him is criminally liable. Now, if the safety cables get prematurely fatigued and break causing the death of 5 people, then it is more or less an unfortunate accident and penalties are less severe.
But please, stop pretending the corporation is some sentient being capable of doing anything on it's own.
