This is a question that many people have about God and Christianity. And after doing some research, I came apon this answer.I hope this helps those who have this question.Please comment if you decide to read.God bless:)

The reason God needed a sinless human sacrifice as atonemnent for sin is because that's what justice is.Have you ever wondered why the symbol for justice is a set of scales? When one side goes down, the other side goes up. In order to balance those scales, when something (sin, in this case) is laid on one of the scales, something must be placed on the other side to balance it out. Do you really think that all the evil that has ever occurred in all of history could simply be "dismissed" without any justice? God provided the balance of justice by offering His Son in LIEU of punishing everyone on Earth, which is really what we deserve. And only a perfect sacrifice would do, so not just ANYBODY could be sacrificed, because we are all sinners. There has only been one perfect, sinless person in all of history and that was Jesus Christ. That is why only He would suffice to pay for all the sins of the world for all time.Justice has been paid. 

However, those who reject this gift are in the position of having to pay for their own sins themselves.

And, it's not, necessarily, Jesus' "death" that was His sacrifice or, even, His resurrection, it was everything leading up to it--Because,not only did Jesus suffer tremendous physical torture before being hung on the cross.He, also, took every kind of physical,emotional,phycholigical, and even sexual pain and suffering apon Himself. That's why, the moment Jesus died, the Bible says that God had to turn His face away from His own Son when He died on the Cross. Because God can not look at sin. Imagine how it would feel, as a parent, to have to watch your own child suffer everything Jesus went through and then have to turn your face away from them at the moment of death.
