I reply to my own post ---

Each action has consequences. The consequence of a legal abortion is the fetus. That such is 'murder', or that the fetus is a person, is contentious. Some consider it a sin. Some do not.

Illegal, back-alley, back-woods, second-story walk-up-clinic abortions have in the past, and will have in the future, consequences to indisputable living persons -- the women at risk in unsanitary conditions, the spouse if made a widower, the other children if rendered motherless, society in general if non-supervised teens roam streets. 

The potentially greater number of living persons affected as the result of illegal, unsanitary abortions is why I consider actions leading to such is the greater sin, and should be considered so even by those who believe abortion to be sinful.
