This may surprise some people but... it's possible that everyone talking to the press about this story thinks they are 100% correct about their assessment. Because there may very well be "good people" on the Russian side who, after Mariupol fell under Russian control, "helped" the family and showed them kindness.

Not everyone in Putin's murder machine is a cold-hearted Soviet Union wannabe. And so, when shown kindness, people who have suffered may truly believe they are now "on the right side."

OR, possibly and simply, the parents did what they felt they needed to do in order to keep their kids alive.
