Matthew 26:47-50 Why did Jesus call Judas friend ?

There is a lost gospel called The Gospel Of Judas. In this gospel, Jesus tells Judas to betray him so that God's plan can take place. Many Christians have rejected The Gospel Of Judas. But how els was Jesus going to get crucified if he didn't arrange for his own death? According to The Gospel Of Judas, Judas was Jesus' favorite disciple. He told Judas things about heaven that he did not tell the others. Of course they were friends.
