The concept of expiation though execution is a matter of dogma, but I doubt that many have given much thought to its
"logic". I found the following artical quite interesting in that regard.
quote:
THE DEATH PENALTY AS AN ACT OF MERCY
The Mishnah’s laws governing the death penalty define a theological and narrative, not a juridical, context in which the passion narratives may be read. The law, Halakhah, forms Judaism’s principal medium of theology and translates details of law into a theological system expressed in patterns of deeds.

Given the Rabbinic conviction that all Israel possesses a share in the world to come, meaning, nearly everybody will rise from the grave, the sages took as their task a very particular task. It was the specification of how, in this world, criminals/sinners would receive appropriate punishment in a proper procedure, so expiating sin or crime that, in the world to come, they would take their place along with everyone else in the resurrection and eternal life.

The
'logic' of Christology flows directly from the
'logic' of its predecessor.
