Judas returned the blood money

Matthew 27:1-14
When Judas, who had betrayed him, saw that Jesus was condemned, he was seized with remorse(悔恨) and returned the thirty pieces of silver to the chief priests and the elders.  “I have sinned,” he said, “for I have betrayed innocent blood.”
Judas threw the money into the temple and left. Then he went away and hanged himself.
The chief priests picked up the coins and said, “It is against the law to put this into the treasury, since it is blood money.”
When he was accused by the chief priests and the elders, he gave no answer,not even to a single charge—to the great amazement of the governor.
Why?
Judas found he had sinned, but it is too late. The sin is he have betrayed innocent blood.
This money is called blood money, Judas has to take his own responsibility.
Jesus is like the lamb before be killed has not any word and quiet. It is shown as the Scripture says.
How?
Do not do the thing that will regret later. Before made decision think it one more time with wisdom and love. Do it good to others.
