Your question was "you don’t think they will suffer from this loss?" in response to someone reflecting on how some kids survive suffering. Your empathy feels toxic, and your question feels in bad faith.

In the face of tragedy, you can't let someone morally and ethically aligned with you go unreprimanded because you perceive them as demeaning. The comment did not imply the kids would turn out okay. It implied they would survive.

But you don't get a hit of that sweet moral outrage by agreeing with people.

Life: Sucks

Someone: Hopeful platitude

Reddit: Yeah, that's something I can argue about. For the children.
