God decrees vicarious redemption of Jesus wrong?

It is said that Jesus died to redeem man.

Yet on the cross, our hero Jesus when speaking to God the father asked, why have you forsaken me?

This indicates to me that the sacrifice that Jesus was attempting to do was rejected by God who decided that all men are responsible for their own sins and that to use Jesus as a scapegoat would be wrong.

Is it moral then for man to hide behind a scapegoat?
Is it wrong, as God indicates, for someone other than the perpetrator of sin, to take the blame or punishment for the actions of others?

Does a God need a sacrificial lamb in order to forgive us as individuals?

This question I pose to believers and none believers alike.

Are you responsible for your actions or is it right to use a scapegoat?
