Yes, let us do as the OP suggests, and let Pope Francis' view on abortion be the end of all discussion on the matter!
After all, Pope Francis said this:
"Human beings are ends in themselves and never a means of resolving other problems."
Which is, ironically, the EXACT OPPOSITE of the kind of policy God used with the Flood of Noah, since God could've simply prohibited bloodshed in Genesis 9:5-6 and appointed Noah to enforce the newfangled law WITHOUT carrying out the Flood (laws were issued which rectified the problem of anarchy, where God forgot to prohibit bloodshed). NOPE: God probably didn't want to overburden Noah with hardened criminals on his hands, so he wanted to give the Earth a fresh re-do with a more managable population of 8.
On the abortion issue, Pope Francis can have the last word just after he answers these questions:
Were there any third-trimester pregnant women who were drowned in the Flood, or any pregnant women who were actually giving birth at the time of the Flood (such that mother and baby drowned), or were there any neonates, infants and young children drowned in the Flood?
God is a moral monster, and the Pope has no business parading about in a pompous hat and robes acting as if he's an expert on morality.
