"Also if she were without original sin; than she would neither want nor need Christ's redemption in any form."
Correct. If she lived a sinless life, she would not need Christ, yet she called Him Savior. The whole idea doesn't square with Scripture.
The person who pulls you out of the way of a speeding car before you are hit would be no less your savior than the doctor who performs the life saving surgery on you had that person not been there.
