Revenge in WWII

Revenge was a huge factor in the battles near the end of WW2. First of all, there was the huge countrywide "ethnic cleanse". This involved all people of different races battling and massacring people of other religions and homelands. Secondly, there were the Russians. All the Russian troops marched into everyone's territory and wiped-out Germans and poles. On their way, they collected civilians and guerillas as extra reinforcements, completely wiping out German troops. They thirsted for revenge for people killed, their homelands being taken, and their property lost.

Hitler sook revenge for losing the war (Which was his problem), so all boys 13 and up were drafted into the military. Some were given suicide missions and an anti-tank grenade to carry them out against soviet armored transports, others sent to guard towns that were immediately carpet bombed. America sought revenge for pearl harbor, so they nuked two of Japan's cities, one of which was the center of Christianity in Japan.

Many people died in the name of revenge, which started an endless loop of murder and death, and caused many different cultures to hate each other so much that the hate still exists to this day. If WW2 had less revenge-driven motives, there would have been much less murder.
