Contractor

The general watched the wall of his headquarters shake apart and collapse.
The contractor smiled and said “This will give us an opportunity to learn from our mistakes and rebuild better.”
He was the first to die.
A year later, investigators found the contractor criminally negligent, and they imposed a heavy fine on his company.
Which was already bankrupt and out of business.
The fine would have barely paid the cost of the investigation and prosecution. Or the burial and death benefits of the soldiers who died during the attack.
At least nobody survived. Medical costs would have been astronomical.
