I think Aunt May being on Her death bed would be a good idea because it makes Peter do the righ thing and to never give up such as what spidey said about ASM Issue# 33 (great Issue by the way). Aunt May is ill and Peter can think of Her and realize that if He dies, then Aunt May will have nobody to take care of Her. Aunt May has always been the one to drive Peter to do the right thing. Aunt May should also talk with Peter on Her death bed and have something similar to ASM Issue# 400, where Peter and Aunt May are talking and Aunt May says, "it's my time" which is truly sad. If they put something similar to that on Film it's going to be a sad moment and a great scene. And I agree with chaseter about Aunt May telling Peter she has always known He was Spider-man, but have Her say it on Her death bed, and that would make the scene even more emotional.
