As we consider the historical perspective, humans This condemnation led early Christians to accept have deliberately and knowingly inflicted on one pain as a normal consequence of Eve’s action and to another many experiences associated with pain— view this consequence as being directly transferred from the earliest wars to the more recent irrational to them.
