It survives by making billions in profit which is it's goal.
People have such a myopic perception of the world that it's alarming.
If this incident materially impacts Disney's profits, heads will roll. If it doesn't (and it won't), they won't.
This is not to excuse Disney for their negligence here; nor it is to suggest they aren't guilty of gross negligence, but let's assume the latter is true.
What should happen? The ruination of Disney the corporation? The loss of thousands upon thousands of job and all the dreams of kids around the world? That's justice?
In order for significant punitive damages to be awarded, there will have to be evidence that Disney was fully aware of a material risk from alligator attacks and willfully chose to ignore it for profit motives.
The fact that there have been millions of visitors to this hotel and only two alligator attacks over, I believe, at least a decade, doesn't make the case that the risk was clearly obvious.
Having said this, they could have and should have put up "Beware of Alligator" signs and so they were negligent.
Millions of people are negligent each and every day of the week. We have an ancient Common Law system to which Insurance has been tacked on to deal with this fact in a fair and reasonable manner.
People make mistakes. If every mistake led to the ruination of the perpetrator, it would be a sorry world.
