I have been asked this question by a correspondent (of a different opinion set).
An answer is not easy at least for me to justify to another person as we disagree even on what are the facts that relate.

If a person is evil, is it from their actions and effects, or by intentions?

Your opinion? I prefer an answer from an Objectivist standpoint rather than a religious one.

What well known names in the media today would qualify for a loud and clear- Yes?
