Jesus didn't command us to baptize. See the first verse in this post. As for the thief on the cross, Jesus is the sovereign lord and can save whomever he wishes. He still commands us to baptize believers. Baptism is required if you want to call yourself a Christian. It is a commandment of Jesus Christ that we are baptized is that not true? Finding a situation where one person wasn't baptized and still was saved does not negate the sacrament of baptism. That is something some churches made up. I would recommend that you learn about the teachings of the old church instead of these modern forms of the faith.
