Well, I am unsure how to answer yer first part; but I'll have a crack at the second...
Jesus was "sent" down by "god" to attone for our sins. He had to die to do this. The people who killed him (tha actual individuals who nailed his limbs) HAD to do this, so our 'sins could be forgiven'. As these elements imply a lack of choice, and indeed, much of his execution was 'prophesied' I feel that those involved did not have free-will in the matter; god "made them" do this so Jesus' death could be worth something to humankind. But, as I said, I believe we have free will.....
My theory- Jesus was a super karma beast; from a pantheon of similar, highly evolved "gods". A meeting was held, and the physical force of "karma" was discussed somewhere up in the ether; it was determined that humanity was never going to be free from karmic-bonds; hence one of these super karma dudes offerred his eternal existence so that humans had the chance to begin again. By some law of meta-physics his eternal death would revoke all karmic troubles, and eradicate them- he could do so, as his nature and life was on a scale much vaster then every human at that time; hence, he died (forever), in agony and torment, and with a puff of smoke, dissolved all humans karma; in a sense, perhaps this opened the gates to paradise, or cessation of the endless cycle of rebirth.
However- I don't believe in that either.

:D I think jesus was/is a myth or just a human who died for politcal reasons. As could be argued, the world is no better and maybe worse for his existence.....
BOM. All this above, does not stop my worship of the dark gods



Found this which pretty much sums up my viewpoint:
I believe Jesus Christ, if he existed, had an experience of cosmic consciousness similar to what was experienced by Buddha, Ramana Maharshi, and many other people throughout history. Jesus apparently tried to communicate this experience to his followers as best he could, limited by the language and cultural concepts of his time and place.
It is possible that each of us is a function of what the whole cosmos is doing at a point called here and now. In effect, each of us IS the whole universe looking at itself through our eyes. The universe is conscious and self-aware, a.k.a. God, and this awareness and consciousness is within each of us. In other words, what happened to Jesus was NOT a unique experience that only happened to one man in all history and prehistory, but something that EACH of us can experience directly when we tune in to the consciousness that is the base of our existence.
I read the exact same Bible as the Christians do, yet I see Jesus teaching us the same message taught by Hinduism, Buddhism and Taoism. Consider the following verses along with the interpretation I offer as an alternative to the mainstream Christian interpretation.
--------------------------------------------------------------------------------
John Chapter 10, verses 30-36 (KJV)
10:30 I and [my] Father are one.
10:31 Then the Jews took up stones again to stone him.
10:32 Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me?
10:33 The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God.
10:34 Jesus answered them, Is it not written in your law, I said, Ye are gods?
10:35 If he called them gods, unto whom the word of God came, and the scripture cannot be broken;
10:36 Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God?
The King James Version of the Bible has “the” in italics before “Son of God” in verse 36. This is not for emphasis as some may think, but shows words interpolated by the translators. In this case, they were mistaken. The original Greek does NOT have an article before “Son of God,” which in Greek is equivalent to having an indefinite article. In the original Greek of this scripture, Jesus did NOT say he is the Son of God; he said I am a Son of God. He also quoted Psalm 82 that says “Ye are gods.”
--------------------------------------------------------------------------------
John Chapter 14, verse 12 (KJV)
14:12 I tell you the truth, anyone who has faith in me will do what I have been doing. HE WILL DO EVEN GREATER THINGS THAN THESE, because I am going to the Father.
Jesus says the ordinary humans he left behind (who, according to traditional Christian mythology, are NOT divine as he is) will do greater things than Jesus did. I put those words in all-caps to emphasize them.
--------------------------------------------------------------------------------
John Chapter 17, verses 21-22 (KJV)
17:21 THAT THEY ALL MAY BE ONE; as thou, Father, [art] in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
17:22 And the glory which thou gavest me I have given them; THAT THEY MAY BE ONE, EVEN AS WE ARE ONE:
Again I put some words in all-caps to emphasize them. It seems pretty clear to me that Jesus says we can be one with the Father just as he was. In other words, what happened to him is NOT something unique that could ONLY happen to him, but it can happen to each of us. Jesus even PRAYS that we can experience it too!
--------------------------------------------------------------------------------
Now many Christians will protest that Jesus says quite plainly:
“I am the way, the truth, and the life: no man cometh unto the Father, but by me.” (John 14:6, KJV)
I agree, but perhaps not the way that Christians would like me to agree. It is my opinion that this “I am,” this “me” that Jesus speaks of is the big Self of divine consciousness (not the little self of the ego) that is within EACH OF US and was consciously realized by Jesus.
--------------------------------------------------------------------------------
Here is a plausible explanation of what happened: Jesus tried to explain his experience of cosmic consciousness as best he could, using the language and concepts available to him from the culture of his time and place. Awed by his miracles, the disciples of Jesus missed the point of what he was trying to share with them. They distorted the meaning of his message and worshipped the messenger instead. Christianity does not teach the religion OF Jesus, which was the realization of divine Sonship, but the religion ABOUT Jesus, a castrated version of the Gospel that puts Jesus on a pedestal and says that only He, and nobody else, is divine.
For further study, I recommend anything by the late author, philosopher and “spiritual entertainer” Alan Watts, but especially pertaining to this subject Myth and Religion 3: Jesus, His Religion that I paraphrase portions of on this page. Alan Watts does a great job of explaining eastern philosophies to western audiences, and he is also good at explaining what mainstream Christianity teaches, even if he doesn't necessarily agree with it. In at least one of his audio files, Alan Watts makes the point that if Jesus had been born in India he would NOT have been crucified. When Jesus told others that he and the Father were one, they would have said “Congratulations. You finally figured it out.”
