Since Judas’s betrayal of Jesus likely was a grave sin, why did Jesus give him Communion at the Last Supper?

If Judas did receive Communion—as Scripture appears to indicate (Lk 22:19-23)—then there may be any number of reasons why Christ allowed it even though he had already been plotting Christ’s betrayal (Lk 22:3-4). Two possibilities include: Christ may have hoped that the grace of Communion ultimately could save Judas’s soul. Judas did indeed feel remorse for what he did (Mt 27:3-4), although he chose the wrong means to demonstrate that remorse (Mt 27:5). Or perhaps Christ respected Judas’s free will, just as he respects our free will, and so did not deny Judas Communion even though he apparently did not have faith that it was Christ’s body and blood (Jn 6:66-71).
