There was an off-the-cuff line back in Ch25:

Back in the old days, whenever magical identical twins were born, it had been the custom to kill one of them after birth.

I wonder if there is something more to a magical twin connection, that may have even caused problems (confusing the source of magic?), or if this was just a comment on how dark/backwards things were in the old days.

I think it was mostly something along the lines of "there's no point, you're just going to have two of the same person."

One does not customarily kill newborn children merely because they're "unnecessary".

Preislamic arabs were infamous for that kind of post-birth birth control. Romans also practiced the same thing: a roman had the right and privilege to kill his descent whenever and however he saw fit. So, it's customary when it's customary.

... Yes?

Just because it was "done in the old days" doesn't mean it's the right thing to do...

I think the issue is more that it's not a very compelling reason to kill a newborn even by ancient standards.

I suspect it's more to do with two identically-minded people being fundamentally creepy and/or dangerous.

If everyone else ultimately acts primarily in their own self interest, but identically minded twins value each other equally to themselves and always cooperate, and see themselves as an in-group of two to which everyone else is an out-group (which may be a natural result of being able to compare all those different-from-you people to someone who's completely the same as you,) then they might be a nuisance ranging to a major hazard to the rest of society.

If Fred and George's mischief making is typical for wizarding twins, it would explain why ancient society wanted fewer of them.
