[Star Wars] Why was military unit cohesion doctrine changed so drastically from the Republic to the Empire?

During training, Republic clone trooper cadets automatically failed an exercise when they left a man behind. In the Imperial Stormtrooper Academy, backstabbing and opportunism during training was not only allowed, but also encouraged.

The training and styles of the soldiers reflect their governments. The Republic was "good" so they rewarded selfless and heroic actions in their soldiers. The Emperor on the other hand couldn't care less if his troops were respected and probably preferred them to be feared, so his doctrines reflected that apathy.
