Guys, guys, we're all basically children of Satan.
From a behavioral perspective, this - spiritual state of salvation is a different matter, but that's for another time. Besides, King David was saved when he committed adultery and murder - luckily, salvation isn't about the good we do, it's the good work that Jesus Christ did on the cross. We all have the capacity to commit evil, and denying the temptation to do wrong is a battle for everyone, Christian and non-Christian alike, and which is why society must punish wrongdoing severely. We are not all basically good, and one simply has to read a newspaper to figure that out.
