What seems to be bad is not communicating your emotions. Like being sad but not showing it, because you want to show how strong you are. But it is not exactly that here. "Who cares" is not something you do for others, it is something you do for yourself. And I don't think it is bad, at least compared to the alternative, which is feeling helpless because something horrible happened somewhere and there is not much you can do about it, you may try, but then another horrible thing happens and you really can't do anything about that one, and again, and again...
