I think there are many things at play here.
First and foremost it's "Ignorance" in the farthest sense of the meaning here.
They just don't know how to deal with something like rape and violence and so forth, even more so when inflicted on children - and maybe to a degree that's understandable - more or less.
What's less understandable, and this is also big chunk of it all, I suppose, is that people would have to acknowledge that their own life has been far better from the very start - because these horrible things did not happen to them.
In acknowledging that life is just not fair, especially when children art hurt and abused, they would have to acknowledge as well, that it's not completely easy or even possible to be "a normal, productive member of society" (and from their perspective, that is what they are due to their own "hard work"...). And this of course is a garbage attitude.
This whole train of thought reminds of the fact, that people use "victim" these days rather often as an insult.
As if it's your fault to be a victim. The very definition of the word contradicts that. There may even be a part of the population that conflates weakness with victim-hood in general. This is and would be indeed infuriating and grotesquely moronic.
