Is the "thief on the cross" proof that baptism isn't necessary?

How does one respond to a Protestant that says the “theif on the cross” proves that one doesn’t need to be Baptised to be saved - all we need to do is confess our faith to Jesus?


How do you know the thief hadn’t been baptized? But even if he hadn’t he clearly underwent a conversion at some point and it seems that he would have desired baptism before his death had he known of its necessity. That would have been good enough as the Church teaches that, in such a case, the desire for baptism brings about the fruits of baptism (cf. Catechism, 1258).
