That's what they'd like us to believe, I'm sure, as it excuses their malignant narcissism. But not everyone has committed evil acts. Far from it.
"But not everyone has committed evil acts. Far from it."
Exactly. Everyone has sinned, and sin is always wrong, but sin does not equate to evil. Evil is the deliberate choice to sin against another person or persons repeatedly, with full knowledge and awareness, for the pleasure of it. My spiritual partner and I also differentiate in our discussions between what we call small "e", or everyday evil, and capital "E" evil. This article is talking about big "E"-- an example of small "e" would be the petty office tyrant who takes pleasure in verbally abusing the people in his power. I find it a useful distinction.
Sin is the first step on the path that leads to evil, though, which is why we are meant to fight against it. We won't ever win the fight completely in this life, but resisting it keeps us from moving down the path.
