You know, this reminds me of a story with the Wally West Flash. He was bemoaning that even with superspeed he couldn’t always be in time to save everyone. Max Mercury then led him on a journey: Accelerating to near-lightspeed, the two of them ran through a frozen world where thousands of tragedies great and small were happening at that moment. The point being that there was simply more than any person could ever deal with, and Wally would simply have to accept that. This video looks llike something they might have seen.
