IF Jesus existed,(and archaeologists have never been able to verify that Yeshua Ben Yosef did), he was possibly a great teacher and leader of his people. As for son of god, even Christians admit that in his supposed lifetime, he NEVER ONCE admitted to being such. He NEVER admitted to being a messiah either. He preached the word of the day, as did many other prophets of the time.
Why he was crucified by the Romans was that he denied his relationship to the Jewish god, and therefore the Jews turned on him. When questioned by Herod and Pilate, he denied being the messiah and therefore took the punishment. Crucifixion was a punishment by the Romans for breaking the law, and the Romans thought that he may have been an insurrectionist. His comment on the cross (going by scripture) does not prove kinship with a god, as everyone who prayed to their deity referred to said deity as Father (or Mother in some cases). Matter of fact, it can't even be proven as to the existence of the disciple either, because no physical remains have ever been discovered or proved to exist. We only have folklore to show of any existence, and for all we know when constantine commissioned the bible in 312 CE, all 66 books could have been written there and then.
