The mockery alone would have made the crucifixion unbearable. "Save yourself," would have cut to the heart when you knew you were hanging there to save others and you were, in fact, saving them by not saving yourself. The Greek language has many words for ridicule and making fun of someone. They must have been a sarcastic bunch.
The details Luke chose to include give us all we need to believe, yet are somewhat mysterious. No one else records the speech with the daughters of Jerusalem nor the criminals repentance. This is here that we might know it is never too late! Jesus came into his kingdom that very day. And the thief on the cross came with him.
The soldier and the crowd were affected by the eclipse and the experience of watching Jesus die. This was not a normal execution.
Luke is very explicit about the tomb. He describes the construction of it (hewn out of a rock), the newness, the location (the women followed to see for future reference). He is explicit about the linen cloth. He is setting us up for the resurrection!
