Exodus 32:31-33
"And Moses returned unto the LORD, and said, Oh, this people have sinned a great sin, and have made them gods of gold. Yet now, if thou wilt forgive their sin--; and if not, blot me, I pray thee, out of thy book which thou hast written. And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book."
Numbers 35:33
"So ye shall not pollute the land wherein ye are: for blood it defileth the land: and the land cannot be cleansed of the blood that is shed therein, but by the blood of him that shed it."
Deuteronomy 24:16
"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."
II Kings 14:6
"But the children of the murderers he slew not: according unto that which is written in the book of the law of Moses, wherein the LORD commanded, saying, The fathers shall not be put to death for the children, nor the children be put to death for the fathers; but every man shall be put to death for his own sin."
Ezekiel 18:4-20
"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."
Psalms 49:7
"None of them can by any means redeem his brother, nor give to God a ransom for him"
Based on these scriptures, God doesn't seem to want someone who has not done wrong to pay for someone who has done wrong.
