Jesus did die a horrible death on the cross... but so did peter an many others.but Jesus not only died a horrible death upon the cross but also had the WRATH OF GOD poured on on him for us. so not only was he tortured physically for us but also spiritually... just think about that for a moment... he had the wrath of God for every sin of every one on him for us... that's true love right there.
2 Corinthians 5:21
For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
