You would have to throw out the entire book of Romans and much other New Testament text to achieve a Christian faith that does not teach death as the result of sin. Which is fine to believe, but it is wildly inconsistent with historical Christianity.
FWIW, I was raised in a Christian family, hung around a lot with fairly Christian people, and was a Christian myself for several years -- and discussions on this BBS were the first time I ever heard of Christians who believed that death was caused by sin.
