White Devil

During the European colonization of North America and the sweeping mindset of "Manifest Destiny," millions of Native Americans were displaced from their homes and ancestral grounds. Although the term Manifest Destiny wouldn't be coined for about 350 years after Columbus discovered America, it persisted in the European mindset almost immediately until all of America was colonized. In doing so, they not only mercilessly established their power over the Native Americans, but also created a slave trade that would have reverberating consequences still felt in the present. In such a greedy mindset human liberties were pushed aside for material gain of the "fit." Because of this, it is easy to understand the perception of white men from the Natives and Africans as monsters or devils. 

Before any European set foot in the Americas, Native Americans roamed the land in tribes. Most tribes followed their prey and never really had a permanent home. The natives didn't believe in owning land, they only used the resources provided to them, thanked their gods and tried to survive. When the white men started coming, they were tricked out of their lands via "treaties." Because the Europeans were much more numerous and powerful, natives were forced to move into lands set aside for them. All because they unknowingly "signed" a piece of paper they couldn't even read. In their greedy ways, the Europeans exploited the natives' lack of knowledge or concept of owning land. To the natives, the white man had tricked them out of their homage and customs. They called and even depicted Europeans as demon tricksters calling them, "White Devil." Although this is not a direct monetary example, land to the Europeans meant power and money. 

Now, going so far as to say money creates monsters, I think would be a bit of a stretch. Not everyone with money or power is viewed as a monster or devious. I think a more accurate description would be that power can be corrupting and it takes a certain level of self-control and wisdom to keep from creating a somewhat monstrous image. People in power tend to have the responsibility of making decisions for thousands to millions to billions of people. These actions can have positive or negative reactions both from the people the decision is made for, but from those the decisions are made on too. In the eyes of the Europeans, most felt they had the right to conquer as much land as they could find. However the natives felt much the opposite but were powerless, thus creating the inhuman image of a white devil.
