Isnt here the typical connection in the teaching between that what Adam lost
"human perfection ..which .... carried with it the right to life"
and
what Adam's offspring receives back after ransomed and what it will possess in the paradise earth:
a life of human perfection with the right to life ...but not more, no automatic eternal life, but further obidience and testing- The offspring is only ransomed and simply brought to the state it would have been withouth Adams sin, Jesus ransom only accomplishing this and not more. The offspring will have to prove loyal as it would have been in the original paradise. The tree of life yet far in distance.
I think this reasoning is behind the Rutherford-theology.
The situation in paradise will not be much different:
if you not obey, you will certainly die and lose your right to live, nothing would have changed at all since the days of Adam, even after Jesus ransom (ransom for release of consequences for offspring)
Adam had no eternal life, he had the right to live, he could die, his perfection was simply a right to live, a limited perfection namely consisting in a right and promise not to die if obiedient, and this you will get if you belief in Jesus ransom, Rutherford taught, (If i err please correct me)

As the ransom sacrifice concept of Rutherford RANSOM is only for the OFFSPRING, it is not working for Adam and Eve themselves consequently. They are indeed lost. What is not righteous because they did it not of own free will but they were seduced.
