A chat on 4chan

(John 13:21-26): When Jesus had thus said, he was troubled in spirit, and testified, and said, Verily, verily, I say unto you, that one of you shall betray me. Then the disciples looked one on another, doubting of whom he spake. Now there was leaning on Jesus’ bosom one of his disciples, whom Jesus loved. Simon Peter therefore beckoned to him, that he should ask who it should be of whom he spake. He then lying on Jesus’ breast saith unto him, Lord, who is it? Jesus answered, He it is, to whom I shall give a sop, when I have dipped it. And when he had dipped the sop, he gave it to Judas Iscariot, the son of Simon.

Am I understanding this wrong or did Jesus purposely select Judas to be the traitor right in front of all the other Apostles? Why then where they so shocked at the betrayal? 

Jesus had to explain to them that he needed a traitor for his plan to work, and one of them would have to perform the dreadful task. Betrayal was necessary to fulfil the scriptures (Matthew 27:9): “Then was fulfilled that which was spoken by Jeremy the prophet, saying, And they took the thirty pieces of silver, the price of him that was valued, whom they of the children of Israel did value.” 

Why would Judas need to identify Jesus with a kiss if he was the most recognizable man in Jerusalem?

Judas wanted violent revolt to kick into effect to reclaim the holy land for the jewish people His intentions seemed good in his worldview but ends dont justify the means. Means justify the end and he was not justified killing God himself to win Gods favour.
