It seems, for some people, compassion is seen as a weakness.
I don't wholly understand that, but a lot of people have less concern over the taking of children from parents because they consider latinos sub-human by buying into Trumps depiction of them categorically being rapists and criminals. That is also the basis of and how the Nazi movement justified mass murder. I don't think that the US could go down that road anytime soon, but it is distressing to see how little people recognize the current situation as not being unique.
I guess that is why history is prone to repeat itself.
