The context of Romans 6:7 is that Paul is likening Christiam baptism to a symbolic "death" [the baptismal water where the baptized is submerged is symbolic of the grave burial]. So, when someone is baptized, he 'dies' and his sins are therefore acquited. In Paul's theology, it's BAPTISM that erases sins, not someone's own physical death. Of course, that's at odds with what the apostle Peter taught about baptism and sin ... but of course the JW's won't admit there's a contradiction.
