I agree with you in some respects, but it's also possible that the meaning of Jesus' terrifying death followed by his resurrection is a spiritual signpost towards confronting our own fears of death, and towards giving up our selfish ego-identities, and judgement of 'the other'. 

The Easter story suggests that death is not an ultimate reality or something to be feared above all else, and that the 'truth that will set you free' is a truth that makes our own deaths pale in the greater light of Existence/Truth/God.  In a sense he did die for our sins (as in 'because of our sins' - of ignorance and blindness), and to show that bodily death was less important than this great Truth. 

The parts of Christian theology that make his death into an atonement, accepted as 'payment' for other people's sins by a judging God sitting on a throne, seem off base to me. As does the requirement to believe in 'bodily resurrection'. But then wiser people than me through history seem to have believed it.
