How does Judas’s role in the Last Supper relate to Paul’s warning in 1 Corinthians 11:27-29?

Matthew 26:26 (KJV): > And as they were eating, Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, Take, eat; this is my body. 1 Corinthians 11:27-29 (KJV): > 27 Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. 28 But let a man examine himself, and so let him eat of that bread, and drink of that cup. 29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body. How does Judas Iscariot’s participation in the Last Supper illustrate Paul’s warning in 1 Corinthians 11:27-29 about partaking in the Lord’s Supper unworthily, and what are the implications of this connection for the practice of communion in the Christian community?
