Nothing could be more Jewish than the blood curse, except maybe Judaism arguing with itself about it.
When Pilate saw that he could prevail nothing, but that rather a tumult was made, he took water, and washed his hands before the multitude, saying, I am innocent of the blood of this just person: see ye to it. Then answered all the people, and said, His blood be on us, and on our children.
-- Matthew 27:24f.
The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him.
-- Ezekiel 18:20
Jesus certainly didn't get the memo:
... the blood of Abel to the blood of Zechari'ah ... shall be required of this generation.
-- Luke 11:51
The Torah was divided on the subject:
The fathers shall not be put to death for the children, neither shall the children be put to death for the fathers: every man shall be put to death for his own sin.
-- Deuteronomy 24:16
Thou shalt not bow down thyself unto them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me.
-- Deuteronomy 5:9
