I think you miss the point of the question. AC wants to know why we just bombarded a planet with our debris -- scarring another world rather than take the extra fuel to clean up our mess and avoid adding to the craters on Mercury. This is a sentiment I've heard elsewhere -- that the extra science time wasn't worth the environmental cost of dumping our stuff on Mercury.
AC: What you miss is that Mercury is a lifeless rock already marked by tons of craters. One more makes little difference. There wasn't any benefit from the view of anyone working on the project in avoiding impacting Mercury. If this were Mars or someplace that humans might one day live, that would be different.
