It also believes that some people are inferior to others based on these traits. This may lead to hatred of the group that is believed to be inferior.

Answer:
Social Darwinism cultivated the mindset that Europeans were biologically superior to any other culture or civilization. As a result, they believed it was their right as a "superior" group of peoples to take over "inferior" countries and "civilize them" (enforced european practices or economically exploited them). Their mindset: if they were a superior group of people, they were allowed to take over in order to ensure they do what is best for human evolution as a whole.
