Just leaping in with a polite, respectful grammatical observation: The "the Jews who killed the Lord Jesus" does not include all Jews or even most Jews. Those responsible for His death, who "killed him" were not apostles or disciples...all of whom were Jewish. They were what Jesus describes in the Revelation "...a synagog of satan..." bent on opposing the Word of God, and fulfilling the Promise they despised. They were not all of the Sanhedrin, like Joseph and Nicodemus, who opposed the assassination of Messiah. And you cannot safely include those for whom Jesus prayed, "Father forgive them...they don't know what they're doing." The new converts on the day of pentecost were absolved. Those who converted were all absolved. Saul, who at first approved, was absolved in the end.
I think you have been mislead in your reading, and it's good to examine the grammar.
