An Ultimate Question for the Pro-Life

Now, suppose you’ve slipped into somewhere in Austria of summer, 1888.
You can see a lady in front of you. Her name is Klara Hitler.
She is in her 2nd month. The unborn child is a boy, and afterwards he became a man who controls the world.
If he wasn’t born, many Jewish, Polish, Gypsies, or other minorities shouldn’t have been tortured under his policies against humanity.
If he wasn’t born, some certain European countries shouldn’t have suffered humiliation of invasion / occupation.
If he wasn’t born, maybe your grandfather, grandmother, or their close family or friends shouldn’t have been killed.

Are you still able to say that you’re pro-life?
