They could be jerks, but at the same time, we could too.
People who have never ever caused any harm to others in one point of their lives in any way, just simply don't exist.
Which doesn't mean we're all evil to the bone, but the human race was never built to live their life in a way humans expect each other to live, if you know what I mean.
Yeah, people have the right to call others "c***s" for what they do, but they don't and never have the right to call themselves "saints" in any way.
