Yes. The wedge also symbolizes an exit to freedom (visually), and eliminating it would make the escape even more hellish and generally provide for a tighter, more focused composition.
As I thought about your point, Slobodan, I have to go back and agree with Russ. Well, I still see your point, but here's the thing:
Either I'd have to crop the image, as you say, but then I'd have to re-name the work No Escape From Hell
... or ... I leave the image as-is with the perfect title already in place.
Since a cropped image is preferable to an un-cropped image, and since I actually formed the idea "Escape From Hell" as I was photographing the moth within the flower, I do believe keeping the image as-is (with the original title) is being "truer to my original vision" than would be cropping the image and changing the title.
Therefore, the image and title stay ... with an honorary asterisk for your suggestion
