It’s not fair at all, but it is very effective in bringing order to disorder. It’s often a ham-fisted, last ditch effort of a leader who senses they are losing control of the troops. It’s not very popular among the troops and should be used only sparingly. Redemption comes with the re-institution of order, which the troops appreciate. If it is used too often, or arbitrarily, disorder will ensue anyway in the form of rebellion. All good leaders know this. Idiots and sadists don’t, or they don’t care. In this case there maybe pressure on the leader from higher up. Possibly an urgent time restriction, possibly objectives have not been met on the leader’s part. I would suggest cooperation on your part and, if you feel it expedient to do so, make your complaints to your parent, and upon their advice, or principal.
