Jesus' suffering was not a divine plan of "atonement" by God. It was just an event that the Christians blew out of proportion.
In Roman-Judea many people were crucified for a variety of crimes. In the gospels he claimed divinity in front of rabbi's in John 8:58 by saying "before Abraham was born,
I am." That was the final straw for the rabbi's, who ultimately got him crucified. However, from a Muslim perspective, Jesus never claimed divinity. We do believe that he is the Messiah, and because he claimed that role the Jews wanted him killed. They considered him a liar/witch when he claimed the wisdom of the Injil and preached it. He probably also renounced the Sanhedrin/Talmudic Laws which the Temple forced on citizens. So there are many reasons WHY this episode occurred.
He didn't really suffer(asides from crucifixion) so much. In fact he survived and lived long, by God's grace. Ayub was plagued all his life and Abraham was almost burnt alive. So it's not about who suffers the most.
Christians are not confused on this issue. They believe he died on the cross for the sins of all mankind. So it does support their claims if he died that way. They say that no man can do enough good to please an infinite God, and the death of his son was enough for paradise.
