Suppose for a minute, Jesus is God. Then he could have saved himself by calling on 12 legions of angles. So even if I tried to kill him, it's not like he were defenseless.
... It seems Jesus said he could call on angles. And he said no one takes his life, but he lays it down for the salvation of many.
I don't think you can blame the Jews. (A few might include Mary, Joseph, Andrew, James, John, Peter, Bartholemew, Paul, Barnabas, Luke) We could blame them, but it turns out, even I have Jews in my ancestry (about 300 years ago). Maybe you do too.
