It sounds as though many of the children would of been starved or beaten to death, had they not gone for adoption.
So had they not of been adopted, they would be dead.
It was up to the countries involved, it seems to be mainly the Ukraine, whether these children are up for adoption or not and what happens to them, if they aren't adopted.
There are children around the world being left to die of neglect and starve to death, or given to abusers to eventually be killed.
Out of everything that happens, I don't think this "family" can be condemned.
We (the UK/US etc) governments/ UN etc need to work to end child cruelty, but this will be a long time coming, meanwhile these children need placements, that at least keep them physically safe.
