Now you're running into the idea of moral absolutes. If you see something as always wrong, irregardless of the situation with no "it depends" gray area, then it is easy to understand how people who recognize something as a moral absolute can equate inaction as equal to or worse than normal opposition. "Now, we must all fear evil men. But there is another kind of evil which we must fear most, and that is the indifference of good men." (name that movie!).
