How does he know that he does not later travel back in time and give his consent?
He’s had a “great life” because of his parents creating him. Otherwise he would have just been an unfertilized egg flushed down the toilet (or in India), washed out into the street or Ganges.
Out of 1.3+ Billion people in India, that has to be a few nutcases, and he’s one of them.
Since he doesn’t like being created, he can do a male “settee” and make himself into a self-created BBQ.
You want fries with that, Mister?
