Simon Peter = good guy. Thief = bad guy.
Maybe not.
Luke 22:59-60 (NLT)
Someone else flatly stated, “I know this fellow is one of Jesus’ disciples, for both are from Galilee.” But Peter said, “Man, I don’t know what you are talking about.”
Luke 23:41-43
But the other criminal protested . . .“We deserve to die for our evil deeds, but this man hasn’t done one thing wrong.” Then he said, “Jesus, remember me when you come into your Kingdom.” And Jesus replied, “Today you will be with me in Paradise.”
Loved of God. Saved by grace. Both of them.
