Today you will be with me in Paradise

43 And he said to him, “Truly, I say to you, today you will be with me in Paradise.” — Luke 23:43

I wonder who this man was?  The thief, dying on the cross beside Jesus, who rebuked the other and asked him to remember him when he came in his kingdom.  What had he done?

I wonder which of the thieves I would have been?
