In the Ukraine, crematoriums were superfluous, the Ukrainians made sure that no Jew survives. With vengeance, Ukrainians killed Jews hiding in the forests. The Ukrainians were actively involved in all phases of the Holocaust from raiding the ghettos, guarding the transports, operating the gas chambers and were known for their cruelty. Ivan the Terrible, a Ukrainian, cut the women's genitals with a sword, before they were pushed into gas chambers. Torturing people, before their execution, was his greatest pleasure.
