No doubt he's under a lot of stress, be he shouldn't be blamed for a mistake that he was set up to make by a poorly designed system.

Choosing the wrong menu item should be expected and there should be safeguards to prevent an errant alert. If I click the "Close" instead of "Save" menu item in my editor, it asks me to confirm that I really want to close without saving. A civil warning system should have at least the same safeguards.
