From Matthew 27:25, "May his blood be on us and on our children" If they were like any well-documented lynch mob, they would say "Death to Jesus!" "Death to the false prophet!" "Death to the blasphemer!" and consider killing JC to be totally justified and not something grossly negative for them and for their children.
Not sure why you chose that verse for the point you're making (probably one of Carrier's ideas). Just before Mathew 27:25 we see in Mathew 27:22-23, the crowd is crying for Jesus to be crucified.
Matt 27:22 Pilate saith unto them, What shall I do then with Jesus which is called Christ? They all say unto him, Let him be crucified. 23.And the governor said, Why, what evil hath he done? But they cried out the more, saying, Let him be crucified.
* If we see the verses below, we can see the context of Matthew 27:25 is different from the context you give in the quoted above. in bold*
Matt 27:24 When Pilate saw that he could prevail nothing, but that rather a tumult was made, he took water, and washed his hands before the multitude, saying, I am innocent of the blood of this just person: see ye to it. 25 Then answered all the people, and said, His blood be on us, and on our children. 26 Then released he Barabbas unto them: and when he had scourged Jesus, he delivered him to be crucified.
