No, it’s not. It’s to engage it best.
Take two cultures: one that executes leaders for making bad calls and one that judges them according to what they knew when they made the decision. Who wins?
We’ve run this experiment hundreds of times because it’s appealing to think steep consequences for bad decisions leads to good decisions. But it doesn’t. It causes caution and indecision. The example that comes to mind is Carthage vs. Rome; the former executed failed generals while in Rome "defeated generals seldom faced serious punishments" [1].
