I very seldom use the

emoticon for things that people write here on FSU. In your case, however, I must make an exception.
The only reason why the baby ever was born was because his mother left the U.K. and met the baby's future father. To say that the baby
died because of the very events that gave him life is ridiculous.
The mother then
gave birth in a refugee camp in Syria and tried to go back to the U.K. with her son, who, like her was a British citizen. Instead of being compassionate and trying to get them out, the British Government revoked the mother's citizenship and refused to let her return home. And, as far as I can see, it made no attempt to bring the baby back to the U.K., as the mother's family wished, and where his relatives would have cared for him.
ETA: Being compassionate does not mean not prosecuting someone for her crimes. She should be prosecuted if she ever steps foot on British soil.
