Why wouldn't different people give different viewpoints about the same incidences? None of the verses you gave contradict what Jesus did at the Last Supper WRT Judas, do they? One mentioned the foot washing, another left it out. So what? Did it still happen? Jesus still reveals that he would be betrayed. This, remember, is not a deposition like would be needed for a court of law where affidavits have to be notarized and signed. Even if it were, when several people give an exact word-for-word description of what happened, it usually means they all got together to agree on a story - collusion, it is called. Such testimonies don't give the impression of it being true. The books that were written down came about after several decades after the fact yet the words Jesus said and the truths he taught were being passed on orally all during that time. And whatever they told about Jesus didn't change once it was committed to the written word. So, not only were these letters given to the churches under the authority of the Apostles, they matched up with the truth as it had been preached before.
What of the 30 pieces of silver Judas received? Matthew tells us: Then Judas, which had betrayed him, when he saw that he was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders.... And he cast down the pieces of silver in the temple and departed. But John tells us: Now this man [Judas] purchased a field with the reward of iniquity. So which is it?
From the above link, it is covered in #80:
What happened to Judas? Did he commit suicide or die by a rather grotesque accident? Matthew xxvii, 5: He went and hanged himself. Acts i, 18: Falling headlong he burst asunder in the midst, and all his bowels gushed out. Which is it? Both cannot be correct. Was he questioned by Annas or Caiaphas? Teh writers disagree.
Covered in point #79. I'll not take up space here repeating what is explained at the link.
So many discrepancies.
No, not really. Unless that's what you want to find. Be brave, go to the site and see if your "concern" is covered. The critic sometimes assumes that the Biblical accounts are exhaustive in all details and intended to be precise. This is rarely the case. As such, the critic builds on a faulty assumption and perceives contradictions where none exist.
It gets back to the question of faith, does it not? I spent five and a half years in a Bible College and graduated with a B.A. in Biblical Education and a minor in Theology. NOTHING that you are bringing up that you say is devastating to the authority of the Bible is either new or unresolved. I've studied ALL of these so-called contradictions and it only made my faith in the Word of God STRONGER. You place a lot of trust in "scholars" that lean towards the view you favor. Why not at least listen to what the other side has to say for a change?
The accounts I cited offer contradictory statements about certain matters of fact with regard to the story of the events around the Crucifixion. Thus, as O’Reilly and others have said, the Bible contradicts itself. The contradictions I cited are not reconcilable.
