Who is this ‘our’ you write of? Anyone who ‘blames’ Jews or Romans (and descendents thereof) for His Death on the cross, and the ‘End Times’ need to read the Bible.
What I know, is that I put Jesus on that cross, as did EVERYONE. Only the ‘perfect’ get to Heaven, and those that accept and acknowledge Jesus as their Lord and Savior. As there is no one ‘perfect’ (in otherwords, ‘sinless’), we all need a Savior.
(FWIW, asking Him to be my Saviour is easy, treating Him as Lord of my life? A HUGE struggle for me. Unfortunately, I often fail in that, especially in responding to fellow FReepers, at times.)
God chose the Jews to be His people, as an example to the World, so everything DOES revolve around His City, Jerusalem. The’Law’ was given, to show how we should, but can’t, and won’t, live. Jesus is the Lamb of God. By accepting Him as Savior and Lord, our sins are transferred onto him, as sins were transferred onto the Passover lamb, and His, spotlessness, sinlessness is transferred to us. Passover was/is a foreshadow of Jesus’ Death, Resurrection and His forgiveness of sins.
Anyone who ‘blames the Jews’ for how everything turns out, is blind to the Truth.
Ask yourself first, who is Jesus? Jesus explained the answer to His disciples in JOhn 14:7 ... when you 'see' Jesus you have seen The Father Almighty, in your spacetime as Jesus. ONLY God could pay the penalty price for your sin.
