If there was ever a person that should have never been born, it was Judas Iscariot. In Mark 14:21, Jesus said, "The Son of Man indeed goes just as it is written of Him, but woe to that man by whom the Son of Man is betrayed! It would have been good for that man if he had never been born." If Judas was such a bad guy then we can learn a lot about what not to do. For instance, Judas was a thief and a self absorbed opportunist. His opportunistic propensity made him an ideal candidate for the Devil to manipulate. And when Judas realized the severity of his actions, he chose remorse over true repentance. Judas did not end well. We can learn a lot!
