We know that evil is real. Some will argue that evil is simply "things happening that we don't like," which I think most people consider a shady dodge.
Because we know that evil is real, we also have an idea that justice is desirable. Although we quibble about the details, we know that when "something wrong" happens, we want it to be fixed.
