Hernan Cortes (1485-1547) was a Spanish colonizer and conqueror, who leaded the conquest of the Mexican territories, that started in 1519 with the occupation of Veracruz. The tales about the sacking of the Mexican capital, Tenochtitlan, are still legendary nowadays. After the takeover of Veracruz, Cortes gave the order of sinking his own ships (it was thought they were burnt, but nowadays that hypothesis is being questioned). Anyway, he destroyed his ships on purpouse to force his men to go forward and conquer the New World, both in the militar and spiritual (goal of spreading the Christian religion) dimensions. Agreement with his decision: of course it is an incredibly effective manner of ensuring that his men would be motivated to conquer the territory, mainly because they did not have an alternative choice. They had to become rulers there or be lost in the middle of unknown lands. It can be claimed how the ultimate goal justifies the means. Disagreement with the decision: it can be argued how unethical is that he prevented his men from deciding if they wanted to participate or not on the mission. He eliminated the choice.
Confederate coffers being so low, little food or other aid could be provided for Indians struggling with the challenges of a wartime economy.

It is hypocritical because racism and segregation did not apply if a white person was being tended to by the nurses. This means that while they are not equal or important when it comes to the law they are equal and important if they happen to have a white patient who needs them. And they can't be both at the same time.
