Who gets to judge what is evil?
That's the job of every individual person, and "individual mileage may vary", as you Americans like to say.
However, there are some things that are quite apparently wrong and the vast majority of common people have no trouble recognizing it. It's our elites and their pitiful brainwashed followers who have a problem seeing the plain evidence of their own eyes.
The principles of right and wrong are written on the human heart, including the first principle of ethics, which is that the good is to be done and evil avoided.
The natural law (which roughly corresponds to the Ten Commandments), is also written on the human heart, and is evidenced by its universal recognition by various societies throughout history. The determination of right and wrong in particular circumstances can become a complex process, but the underlying principles in moral calculations are simple.
Evil.
