Some people think that he did not want to be the Messiah. The main reason is because it was such a huge burden/responsibility to bear, and he was just human. It is thought that Jesus actually sweat blood when he knew that he was going to die and this has been proven possible by scientists. Also, you wouldn't be able to lead a normal life, because all the time you would be fighting one battle after another, whether emotional or physical. Some people believe that Jesus is a pacifist and so this is the exact opposite of what you would want to do; all the time people would be dying, even innocent children causing unnecessary pain and suffering. Also Jesus may be scared to die, as a typical Messiah didn't last very long.
The Jews were waiting for a saviour from God which would be called the Messiah. The idea of a Messiah went back to the times when the Jews had their own kingdom. The kings were anointed with holy oil and this is what the term Messiah literally meant, "The Anointed One.". Christ is a Greek translation of this and is in the New Testament, and is basically just another way of saying Messiah.
Although he is named the Messiah by many people, he did not want to be called this at the time which he was living at, as seen in the Bible, Mark 8 v 33. "But turning and seeing his disciples, he rebuked Peter, and said, "Get behind me Satan! For you are not on the side of God, but on the side of men."" Just this verse has lots of spiritual thoughts and ideas on what Jesus wanted people to expect of him. He rebukes Peter, i.e. he is angry with Peter as he is criticising/scolding him. This in itself is a very big thing, but then he goes on to say, "Get behind me Satan! For you are not on the side of God, but on the side of men.". He is telling Peter that he is thinking about man's desires, and his own personal wants, but he is not thinking of the bigger picture with God, the Omniscient; the all seeing one who knows about everything.
The first one to proclaim Jesus the Messiah is Peter (in Peter's confession of faith). He asks his disciples, "Who do men say that I am?". He already knows the answer to this, but he is testing his disciples. But in response to this question, the disciples say various different people's thoughts, not their own thoughts on Jesus but the people of the time who are waiting for this stereotypical Messiah, and so they reply answers such as, "John the Baptist", and "Elijah". But he then asks once more, "But who do you say that I am?" And so Peter says, "You are the Christ." This is such a massive, huge thing to say at the time, because this was the first time that anyone had ever publically claimed that Jesus was the Messiah/Christ.
However, straight after he had proclaimed this Jesus told them not to tell anybody, "And he charged them to tell no one about him." There were many reasons for this. One of the main reasons is that he was unprepared to face the massive swathes of people who would come and attack him, because they did not believe him. There would just be too much force and openly claiming that he was the Messiah would just earn him an early crucifixion, as was common practice for people claiming to be the Messiah. And he was not ready to die yet because he had not spread God's message first. He knew that he was going to die, and he knew when he must die, as said in Mark 8 v 31, "And be killed, and after three days rise again."
He also told them shocking new things, "And he began to teach them that the Son of man must suffer many things and be rejected by the elders, the chief priests and the teachers of the law, and that he must be killed and after three days rise again." He was informing them that he would be rejected and oppressed by the people of high status, and he would be killed and be resurrected again. Peter was astounded by this, and rebuked Jesus, "And Peter took him and began to rebuke him." He just simply couldn't take in all of this new knowledge at once because he had based his life on this. Peter’s "rebuke" of Jesus was due to his still incomplete understanding of the true mission of the Messiah. Peter could not come to terms with the idea of the suffering Messiah with the current Jewish notions and thoughts of him.
In conclusion, I think that Jesus did want to be the Messiah, just not how he was expected to be. He was a peace loving person, and very strong willed. Unless he had a strong passion to be the Messiah, there would be no reason for him to go through so much pain and suffering in his life time as the Messiah, and to have such a painful slow death. There are many things that are still left up to people's own thoughts/interpretations and they can decide themselves whether or not they agree, but I think that he did want to be the Messiah.
