If a heel wants to make indirect comments about a sick child, or if he wants to revel in his own apathy and lack of concern over the suffering of others (yes, even sick children), then I'm cool with that. But confronting a child that's actually sick and making cruel remarks towards them directly? I'm not sure about that. It's not that I'd even have any moral issues with it personally because I wouldn't (although if I had any children of my own - which I don't, nor do I care to - I might feel differently), but there would almost certainly be a tremendous amount of backlash over it, so I don't see any real upside to it.
