The Bible doesn't say what happened to the other criminal. It was a conversation between one of the criminals and Jesus. Nor whether there was any other conversation Jesus had with those two men before all succumbed to a terrible death.My puzzlement comes from why thief number 2 leads a terrible life and then based on a two minute death bed repentance gets to spend eternity in Heaven while the other thief said the wrong thing and went to the other place.
The lesson to be learned from the passage is that we cannot earn our place in Heaven but it is never too late to accept the salvation Jesus offers.
