Eh I don't know, evil is a word that often defines a reason to be bad, deadly, terrorist, and personally I don't think anyone has a good enough reason to be evil and there is little validity to the word itself.
How about you be more specific in who exactly are the evil ones. A whole religion? Or rationally speaking, certain groups or people in such religion?
Its fairly easy to just walk on saying, 'well their evil' but ultimately it is just a mass generalization that isn't true and has little validity itself.
Every religion possess some evil elements I am sure, some more than others, especially lately but in the same context, sweeping generalizations however, can be labeled the same thing as evil since ultimately they are destructive, ignorant, and a cop out.
