This is a familiar take on some of the age-old questions in Batman's character history, namely how far he allows himself to be pushed by grief, and his refusal to take another person's life, even his archenemies and supervillains who repeatedly escape from custody and cause immeasurable death and destruction.

I like the fact that you managed to fit so many different characters from Batman's rogues gallery into this comparatively short piece, and provide some details about how the deaths of Alfred and Robin have affected Bruce.

This piece felt a little short on narrative. We're first introduced to the fact that Alfred and Robin have already died, so the story basically starts with Bruce refusing to be Batman, suffering the death of Jim Gordon, and picking up the cowl again to hunt down Joker and start beating him up (presumably headed toward actually killing Joker this time). There's not a lot of story there that isn't in the form of "telling" (i.e., the narrative just passively says it's happening rather than pulling the reader into the world you've created), and I think the piece would be a little stronger with some more narrative detail for the reader to really sink into.

Overall, I'm a big fan of Batman comics and alternate universe versions of those familiar characters, so I really enjoyed your piece on a conceptual level. I do think there's room for improvement in the execution itself, specifically, but I think you have a really good foundation here. Nice job!
