There were other ways to forgive sin that did not involve something dieing. A scapegoat type ceremoney would have been better because it was used to forgive the sins of a large number of people (and the goat was not killed).
When the Israelites were polytheistic, they use to sacrifice humans to the other gods. Yaweh preferred animal sacrifices to human sacrifices and human sacrifice was removed when they went to monotheism.
So a human sacrifice as a ritual that Yaweh would prefer doesn't make much sense. Jesus as a scapegoat (which is not killed) would make more sense maybe.

The offering ceremonies that were done for the forgiveness of sins in Israel, were just outward gestures required by God for repentence. They were essentially no different than circumcision or baptism. These things are meaningless without someone having faith. Remember, Christ came to atone for all sins - including those of the Jews. Therefore when all is said and done, Christ's sacrifice is the only sacrifice that atone's for sins - which a person takes advantage of by having faith. All other sacrifices for sin are just expressions of repentance.
In Leviticus 16, a goat was used as an offering, and another goat (a scapegoat) was used to bear the sins of the people before God. Both were needed by God to ceremoniously handle the sins of the people. The scapegoat alone was not sufficient. Christ played the part of both goats since He both bore the sins of the world before His Father, and was used as a sacrifice for the atonement of sin.
It is important to realize that God views death very differently from most people. God's perspective is from the forrest. Most people's are from the trees. Christ wears the marks of His death as a badge of honor - which are viewed no less than such by the Father Himself. The suffering that Christ underwent is trivial compared to the things He accomplished, and the prizes He gained for Himself: which were rulership over the new creation, and the elevation of man from his state of disgrace, to co-administrator of creation along with Him.
One side comment relating to things you have written several times before: when God destroy's infants and children among evil people, He is actually doing them a favor. The infants and children are automatically saved eternally, and are spared the almost certain condemnation they would suffer, if they were allowed to grow up and live among the evil people God destroyed.
One other thing: God destroys evil nations not just out of a sense of justice, but also out of a sense of necessity. Too much evil in the world done by people contaminates creation, and the spirits that make up creation that do their duty (e.g. the sun, the earth) are not able to bear it. God therefor has no choice but destroy evil people, in order to preserve the welfare of creation.
