Why is the U.S. purposefully so evil? Killing your black, homeless, mentally handicapped and similar groups is not only morally deplorable no matter what crimes they supposedly did commit (or probably more often than not, didn’t commit), but also allows dictatorships and the like to argue that the U.S. isn’t morally superior to them. Which, after repeatedly seeing such cases and the rhetoric your politics are filled with, is arguably a fair argument to be made.
