So, it's "evil" when the employees die.

But................

What if there wasn't a fire? What if no one died.

Was the action still "evil"?

Does "evil" only apply to the consequences of an act?

A gun is not "evil".

Ever read "Deadeye Dick"? A boy shoots a rifle into the air. The bullet kills a person. Is he "evil"?

Relativism: Not that everything is equal. But that "good" and "evil" are viewpoints. And these viewpoints change.
