Judas didn't want to help the poor. he was stealing from the money box.
he was lying, and almost turned all the apostles against Jesus in that incident.
Christ was being honored - and Judas was saying, don't honor Him.
I really should not be commenting on this conversation because my doing so could be dishonoring to God.
But I guess I will put in my 2 cents.
Jesus was directly addressing the plight of the poor in this world and telling us that we should not be upset or overly concerned about the problem because it will exist through to the end of time.
2000 years later and we still have this growing and unsolvable problem of the poor. Jesus knew that there would be an obsession for people to turn their attention to this worldly matter when there were more serious problems to consider.
The salvation of one's soul will trump over making the poor rich any day.
Peter's first miracle was one where he said Silver and gold, I do not have but what I have I will give to you.
The man's faith in Jesus Christ healed the man. Again that is what the bible is all about.
Judas being a thief is secondary. It is almost sure that almost all of us are thieves before we came to Jesus. We take home pens or stationery from our offices or things even if it costs a penny. It is still stealing.
Even after Jesus was crucified, none of the disciples knew that Judas had betrayed Jesus Christ. And most likely they did not know that He was a thief either.
The purpose of Jesus was not to supernaturally reveal negative things about people that was basically characteristic of most people. Even although He knew these things, He did not teach his disciples to be judgmental about people.
The bible isn't a story book for our enjoyment. It is a spiritual book to teach us about God and His ways and also His ways for us.
