“While they were reclining at the table eating, he said, “Truly I tell you, one of you will betray me—one who is eating with me.” They were saddened, and one by one they said to him, “Surely you don’t mean me?” “It is one of the Twelve,” he replied, “one who dips bread into the bowl with me.”
Mark 14:18-20 NIV
This passage is remarkable because by this time Jesus had already walked with his disciples for three years by this time they had all build really strong relationships with each other and no one had a clue that Judas was the one that was going to betray him. It shows that Jesus never showed favoritism and he always loved Judas just like the other disciples and was still willing to die for him. That is how we should treat everybody even the people that are consider enemies.
