"they should be examining their life choices." based on your world view though. We became a very boring race only optimizing our lives for work. No alien race would look at us and think we are smart spending so much time doing things which do not add value to our society just because we can't organize ourselves better.

Just because we conditioned ourselves like this, doesn't mean its right or wrong.

And this article doesn't give us enough insight to even judge.

Birth control is not perfect. 99% is very little in comparision to the amount of sex happening in a population of 8 billion people.

Not really, no.

Sex has consequences like these people are seeing.

Consenting people can still make mistakes and ruin relationships where if they had exercised better judgment they wouldn't have had problems.

Consenting adults can have sex with each other. There's zero shame in that.

And though having these two partners was unwise for this reason, it's not really a matter of shame so much as one where we should just find a practical solution that doesnt mess with the kid.

No birth control is 100%. We live on a planet were very rare situations are getting published as 'news'. So the fact that you read this news, doesn't tell you anything shameful at all. You are just biased and don't even realise it.

And no you are not allowed to shame other people for their decisions if its not clear that there is a kid getting abused in any way. People are adults and not yours to criticsize if it doesn't affect you or a 3th entity which can't protect itself.

Its your personal opionion you can easily and should keep yourself.

Maybe everyone was aware and consenting.

Interesting bias to blame the woman. How do you know that the second twin wasn't taking advantage of their identical looks to convince the woman it was the same man she had slept with the first time? She may not even have been aware that he had an identical sibling.
