Regarding 'deicide' - I suppose we are all guilty of that one. Christ came to save the lost and HE died for sinners. We are ALL sinners, and by HIS righteous blood we are washed clean ('whose blood of sprinkling, that speaketh better things than that of Abel' -- namely grace and mercy). If one weren't a sinner he could claim innocence -- but that's a null set...
Christ had to die. It was part of God's plan. To blame the Jews for killing Christ is akin to blaming God for his plan.
