Devastated

The stupidity of some people is beyond belief. I'm speechless, but so so angry. A 14 month old GSD bitch is currently giving birth, 9 puppies so far. How awful, a baby having babies. What makes it worse is that she is Loki's sister, what makes it a tragedy is that the father is her brother! In my book it doesn't get worse than that!
Accidents happen, Mikey mated Asha, Blade possibly mated Lia ... but no chances taken, in both cases it was straight to the vets for the morning after injection. It was easily sorted. A pregnancy can easily be terminated, but oh no, this pregnancy has been allowed to go full term. Now a 14 month old bitch has a large litter to her brother. It's so sickening it's heartbreaking.
As breeders, Ian and Tracy are in bits, the owners lied to them over and over again. Assuring them the bitch was neutered they are and now giving them a story that the vets would not spay her at the time. Of course the vets would not spay her at the time they suggest, because with the timing they are giving she would be in season then, the vet would not expect the bitch to then be left with her brother whilst in season!
So what happens now? Should some or the majority of them be put to sleep? Will they have physical or mental abnormalities? Who will want them? The future seems bleak, not many responsible people will want a pup of this breeding, does that only leave poor quality homes with people who want an "Alsatian" available to them? Will they end up neglected or in Rescue Centres? Oh God they are not my responsibility, but I could weep for them! They are here now and I hope what ever it may be that they do their best by them. I hate myself for thinking/saying it but unless there is the chance of a happy, loved life maybe they would be better being put to sleep now, the alternative could be heartbreaking, just devastating.
