I am glad you started this thread
Just the other day I was wondering why people persist with poor doers... going to the ends of the earth to save them... when in reality in the wild they very naturally and very rightly would have perished.
As a breeder of dogs, my aim was to always breed the healthiest animals. This meant, when a bitch needed a caesar due to uterine inertia I had her desexed at the same time and all her progeny was desexed and sold as pets. Any time I have had a fading puppy, I have nutured it and then desexed it and sold it as a pet.
Because desexing reptiles really isnt a realistic option, I think as a responsible breeder culling weak stock is the most responsible and reasonable course of action. The other responsible course of action, would be to keep the weak progeny yourself. That would just be unrealistic, as you would soon have no room to continue breeding. I agree, giving away weak animals is too risky. As a responsible breeder you would be horrified to find out one you entrusted to another had been bred.
I think once we start taking the course of nature into our own hands, we have a responsibility to make sure we are doing so responsibly... and perpetuating weakness is not natural. Personally, I would cull. And I have the highest respect for those that do cull humanely... especially if they are employing a veterinarian for the purpose as this would be an expensive undertaking depending on how many need to be euthanised.
