No. saying you agree with a death is not the same as killing someone.
Asking for someone to be killed is worse than agreeing with the killing of somebody.
blasphemers were stoned, not crucified.
Jesus said he was the son of God and this enraged many Jews, more than somebody simply using the Lord's name in vein. It's astonishing, that after a couple of thousand years some people [like the usual troublemakers on this forum] are trying to skew what happened. So apparently it wasn't the Jews. Wait for it, soon we'll hear that Jesus was crucified with the other thieves, because he himself was a thief. He did nothing wrong! Even those that don't believe in him, believe he was there and was generally just a good guy trying to preach good. There is no record anywhere, from what I have seen, of him being a criminal or anything of the sort.
This is what we don't know, probably never will and oughtn't to rely on the gospels for.
According to Jon though, he probably did something wrong, but we don't know what, or else the 100% righteous and honest, law abiding Cesar would not have had him crucified. Oh yeah there is no possible way he had him crucified, because the Jewish masses wanted it this way, and he didn't want to have problems with them.
