The image's iconic quality predates Batman/Robin. The image of a broken person being held by their loved one is enduring, most prominently in the religious imagery of the Pieta. It's been reused and recycled extensively over the centuries in other contexts. You see it across lots of movies and TV shows too. They may not necessarily know what they're referencing, but all these similarly symbolic portrayals work together to cement its enduring nature.
