Earlier quoted context omitted.
It sound alike you already know the answer to your question. If you ask me, though, I don't see why it's not possible for grave suffering to exist in multiple places simultaneously.
I can tell you why: My capacity to give damns is finite . If you happen to be some saint who has infinite capacity for empathy, good for you. I think most people share my sentiment, though.
It’s just that my ability and will to do anything more than care is lacking.
Presumably if I cared enough I’d donate to some charity, but I feel fixing this kind of stuff is why we have governments with humanitarian aid programmes (which I happily pay for through taxes), which should theoretically be a thousand times more effective.
