What would Mohammed do?

I only recently became aware that some people "blame" Jews for killing Jesus.

I don't quite understand.

According to the Bible, Jesus came to earth to be a sacrifice for the sins of men.

So if Jews killed him, weren't they doing Gods will?

Weren't they helping Jesus complete his mission?

Don't Christian's owe the Jews a thank you?

If the Jews hadn't sacrificed Jesus, Christians would not be forgiven their sins.

Or am I just confused?
