Jesus was going to the Cross to pay for the Sin of the World. Peter didn't like Him sacrificing Himself for jews either.

[Mat 16:22-23 KJV] 22 Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee.
23 But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.
