That's extremely easy to rectify. What verse in the Torah allows a person to be executed on behalf of another person?
Let's see your proof.
the torah allows an animal to be executed on behalf of the person...
the whole torah is an act of substitution...had we not fallen there would be no need at all for any of this...we could speak and learn face to face...certainly no need for sacrifices...
all these sacrifices, temple, its priests and ceremonial laws (not the 10 moral ones) had to be set into place to restore and correct the relationship between Yah and man...it is all a substitution from direct relationship...
ITS ALL SYMBOLIC
sacrifices were never successful in making us perfect again or repaying our debt...but our obedience in doing so merely makes us appear contrite to satisfy the Lawgiver...but the breach separation death remained...
these ceremonial laws were an opportunity to show obedience and fealty and faithfulness to Yah not to make us actually holy, sacrosanct, or perfect...we need Yahusha for that...
I have come to understand that Yah had to sacrifice His own "best" in order to restore the breach caused by sin...the Passover lamb was merely protection in the process of separation from SIN from its death...from the land of Egypt and its foreign gods...
Sin has a curse of death, a result of disobedience being "not of god" and only the obedient are spared and His son was the only perfect obedient sacrifice that was then restored to life again
every sacrifice was merely symbolic foreshadowing to the time the perfect sacrifice would be made by Yah Himself...these animal sacrifices were then allowed instead of the expected person...which was ironically and ultimately only God Himself...to restore us...
