You keep equating temporal with earthly examples by holding up the thief on the cross as your example.
Dismas exemplifies Judgment II. Dismas said that his crucifixion was a just punishment, it was due to him because of his sins. Jesus apparently agreed, because he did not deny what Dismas said, AND he did not get him down from the cross. Dismas, though saved, still had to suffer what was due to him because of his sins.
Your attempt to equate the words of Christ, take up your cross, with Dismas again shows your lack of understanding on how to properly handle the word.
Honestly...what Biblical training have you had? If any?
