There are cases of adoptions not working despite all the checks being carried out over a long period of time, from everything from an individual or a couple being financially secure to having a big enough home and their medical health records being checked, along with counselling and support. It can still go wrong but adoption if very much centering the child and trying to find the best permanent home, hence why the process is a thorough one.
A recent international adoption has been discussed here (Myka and James Stauffer and little boy Huxley). Each situation is different, but Huxley was not made to order and then rejected based on the guilt Myka and James felt, he was 'rehomed ' (vile word to describe what happened to this child) because his adopted parents couldn't cope with his learning difficulty and developmental needs and they regretted their decision and wanted out.
The Twitter thread confirms this man changed his mind based on guilt, or as is referred to on the thread, shame. He couldn't undo the conception, pregnancy and Labour and he didn't want to continue so he bailed and needs others to step in and raise his kid. He is genetically related to this child. He is one of many, many men in America and around the world who have absolved themselves of responsibility for a human being they helped create, and in this case he very specifically took steps and funded the process, buying the pieces of the genetic puzzle and hiring medical professional help to make this child a real human, not an idea, not a bunch of cells in a Petri dish.
It is not at all the same. Abortion is not the same. A man abandoning on his kid/s is not the same.
He commissioned a child into being, felt guilty, changed his mind and called in for others to clean up his mess. He has not only created a person, he has created a traumatised person. The only upside is the child will hopefully receive love and is hopefully less likely to receive abuse and neglect by being adopted, than had the child stayed with him.
If he himself has a heart he will also be traumatised for life, if he doesn't he will walk away and forget about the whole sorry affair.
