So you answer your own question, but wrongly. You appear not to know a darn thing about Judaism, Passover or how 'atonement' works in our religion. Kindly cease distorting our religion to prove something to yourself - it only indicates your lack of confidence in your own religion.
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
