Judas was dismissed and was not included as Jesus instituted the 'new covenant' with his faithful apostles. 'After dismissing the undesirable man from their midst, the master of ceremonies introduced the Lord’s Supper to the remaining faithful eleven, using the unleavened bread and the red wine that were still available at the table'.
FYI - please read Hebrews 12:1-11, 2 Tim. 3:1-5, 2 Tim. 3:14-17,
....Elders (those in position of oversight in the congregation) .... remember that most cases of sin in the congregation involve weakness, not wickedness. They don't forget Jesus’ illustration of the lost sheep, which he concluded with the words: “I tell you that thus there will be more joy in heaven over one sinner that repents than over ninety-nine righteous ones who have no need of repentance.” (Luke 15:7) Truly, “Jehovah . . . does not desire any to be destroyed but desires all to attain to repentance.” (2 Peter 3:9) Judicial committees throughout the world do their utmost to cause joy in heaven by helping wrongdoers see the need to repent and start their feet back on the narrow road that leads to everlasting life.—Matthew 7:13, 14. .....Does this mean that if a Christian succumbs to weakness or stumbles into grave sin, he is automatically expelled from the congregation? By no means! Jehovah is not a coldhearted dictator. He is merciful and understanding. He remembers that we are imperfect. (Psalm 103:14) Jehovah recognizes that "all have sinned and fall short of the glory of God." (Romans 3:23) God has arranged for spiritual help within the congregation so that if a Christian takes a "false step" or even commits a serious sin, he may be lovingly ‘readjusted’ in a spirit of mildness. (Galatians 6:1) By accepting counsel from God’s Word and demonstrating heartfelt sorrow and genuine repentance, one who has strayed from the path of righteousness can "get healed" spiritually.—James 5:13-16.
.....What, though, if a baptized Christian seriously errs and all efforts to restore him are unsuccessful? In other words, what if he stubbornly refuses to correct his sinful course?
......The Bible commands Christians: "Quit mixing in company with anyone called a brother
that is a fornicator or a greedy person or an idolater or a reviler or a drunkard or an extortioner, not even eating with such a man."—1 Corinthians 5:11. Realizing that "one sinner can destroy much good," the apostle Paul commanded fellow believers: "Remove the wicked man from among yourselves." (Ecclesiastes 9:18; 1 Corinthians 5:13) This action prevents the sinner from spreading corruption in the congregation, and it protects the congregation’s good name.—Compare 1 Timothy 3:15 Therefore, disfellowshipping is a loving arrangement because it upholds God’s holy name and it protects the congregation from the corrupting influence of sin
. Also, it demonstrates love for the wrongdoer by encouraging him to repent
and "turn around so as to get [his] sins blotted out, that seasons of refreshing may come from the person of Jehovah."—Acts 3:19.
.....The apostle Paul heard of a case of incestuous fornication in that young congregation, and he gave instructions that the man involved be disfellowshipped. Later, the sinner repented, and Paul exhorted the congregation to reinstate him. (1 Corinthians 5:1, 13; 2 Corinthians 2:5-9) Thus, by the healing power of Jehovah’s loving kindness and the great value of Jesus’ ransom sacrifice, the man was cleansed of his sin. ....One may have ceased the serious wrongdoing for which he was disfellowshipped. Another may have been using tobacco, or he may in the past have been overdrinking, but he is not now trying to lead others into wrongdoing. Recall that even before exiled Israel turned to God, he sent representatives urging them to come back. Whether Paul or the elders in the Corinth congregation took some initiative to check on the disfellowshipped man, the Bible does not say. When that man had repented and ended his immorality, Paul directed the congregation to reinstate him.
.......some disfellowshipped persons will never be ‘revived to repentance.’ (Hebrews 6:4-6; 2 Peter 2:20-22)
