"For if the many died by the trespass of the one man" (Rom 5:15)
"For if, by the trespass of the one man, death reigned through that one man" (Rom 5:17)
"Consequently, just as the result of one trespass was condemnation for all men" (Rom 5:18)
"For as in Adam all die" (1 Cor 15:22)
-A8
Until we ourselves sin however, we are without guilt and without sin. A newborn baby is unstained from sin, they have done no wrong and are not even capable of sinning at that point since they have no capacity to choose between good and evil.
Oh I agree that the consequences of the fall come upon us. We will die, and our nature will lead us to commiting sin sooner or later, but we are not stained the sins of other people.
