I never understood that whole “Jews killed Jesus” thing, besides the fact that the Romans actually killed him (maybe the Italian lobby was stronger than the Jewish lobby back then). I mean, how could anyone kill God? Isn’t God all powerful?

The biblical account of Jesus' final days has him being first tried by the Sanhedrin (a Jewish priestly court), then off to Pontius Pilate, then to Herod (because Jesus was from Galilee), then back to Pilate for final judgment. In this account, Pilate demurs from sentencing Jesus personally, but instead presents Jesus to a mob of Jews that have gathered outside the court, and asks the mob if they want Jesus freed. The mob demands that Barabbas be freed instead. The Gospel of Matthew account then has Pilate disclaim responsibility for Jesus' death and has the Jewish crowd accept Jesus' blood on their head for themselves and all their children:

That one line from Matthew may have caused more suffering for more people than perhaps any other single line in the whole of literature.
