Why is Pontius Pilate blamed for killing Jesus in the Apostles' Creed?

In Apostles' Creed , the name of Pontius Pilate is forever associated with the infamy of being Jesus Christ's persecutor. >I believe in God, the Father almighty, >creator of heaven and earth. > >I believe in Jesus Christ, God’s only Son, our Lord, >who was conceived by the Holy Spirit, >born of the Virgin Mary, >**suffered under Pontius Pilate,** >was crucified, died, and was buried; >he descended into hell. >On the third day he rose again; >he ascended into heaven, >he is seated at the right hand of the Father, >and he will come to judge the living and the dead. > >I believe in the Holy Spirit, >the holy catholic and apostolic Church, >the communion of saints, >the forgiveness of sins, >the resurrection of the body, >and the life everlasting. Amen. My question is, why did the authors of the Apostles' Creed include Pontius Pilate as the one who killed Jesus, and not Judas Iscariot or the Pharisees? From this resource I found (which I am not sure presents a convincing argument), quoting Fr. Hardon, it is because > it has been “apostate Christians who have used the State to crucify > the martyrs of Christianity.” > > Pilate symbolizes the sufferings and persecution of the Church, which > is the Mystical Body of Christ. That doesn't seem to explain much. Even if this explanation is true, one can still ask why did the *Apostle's Creed use Pilate to symbolizes the sufferings and persecution of the Church? Why not use someone or the Roman Empire else*? So, why did the authors of the Apostle's Creed pen Pontius Pilate as the one who killed Jesus, and not Judas Iscariot or the Pharisees?
