You're looking for a program which will decide for itself what files to delete - it will somehow know what ones you don't want?
I think that's going to end in tears quite quickly...
At some point after being shown a list of duplicate files, you are going to have to look though them and decide what to keep.
Software can't do that for you.
True, you could just tell it that having found duplicate files, it should delete them without comment - but that's probably not a very good idea unless you're certain the duplicates can be safely thrown away.
