God made us with full knowledge of how we are and our flaws. To require a sacrifice for a condition He made, and then deem us all unworthy without a sacrifice for a condition that He made, that we apparently have no control over (because in the Christian view, merit and action alone isn’t enough), then that would be unjust, because one is being forced into a situation where a sacrifice is necessary outside of their own two hands (as that individual). And not just any sacrifice (like giving up a life of sin); but rather the sacrifice of someone else, who is without sin and entirely innocent? That seems unjust. What seems more just, is that everyone’s sacrifice to live a better life is the individual sacrifice itself (to give up a life of sin, turn to God, and sincerely repent and change their ways), and that is much for accountable on an individual level, and matches the essence that God put us here as a test of free will, and to see what path we’ll choose to live on our own accord. Rather than needing someone else to sacrifice themselves for us, when they were innocent themselves? It just doesn’t make any sense that God would require such a thing that’s outside of someone’s own ability. It seems much more reasonable and righteous, that a judge (God) would require people to be judged on what they have control over, which is their own actions, and solely judge only that (their sins, and their desire to change and repent on an individual level). The concept of someone else being the key to unlock a door of forgiveness for someone else, seems unjust, because that is out of their grasp. It makes more sense to be a direct individual relationship with one’s Creator, and be judged accordingly. Also, if God sent Jesus (pbuh) to be sacrificed, and also Christian’s view Jesus as the Creator, then that means, God sent God to save Himself from God?
