Fellow Christians, why do we keep blaming Jews for the death of Jesus?

When Jesus himself even preyed to God to forgive them, and he himself (Jesus) forgave them for what they have done? And out of the unwillingness of their hard to accept Jesus, Christianity was born? We ought to thank them and learn the the laws of God according to Moses, for Jesus himself said, he came not to destroy the laws but to fulfill the law, and as Jesus also said "Pick up your own cross and follow me". If you will argue about what Jesus said "This is the new and everlasting covenant", then didn't the Lord Jesus Christ observed the Jewish Law, Did he not love the Temple, for as i can recall, he cleaned the premise of the Temple for his Love to God, the same God that the Jewish worshiped. Certainly, Jesus would never want for Christian to cast their hate unto them, but rather would want you to extend your care for them as he did.
