Sure it is. These "personnel who make bad decisions" are accepting money as recompense for their role as mafia enforcers. Just-following-orders is a corrupt moral position which has resulted in the deaths of a lot of innocent people.
I understand that when you think of corruption you are assuming several magnitudes greater recompense but you have to remember how the little folks live.
That is a problem. It might be poor training. It might be bad policy. It might be personnel who make bad decisions. Or some mix of all three.
But it isn't corruption.
