At least you could have included the original unchanged files as a patch to your mod would have been better.
Sorry but not many people upload a backup of all files modified by the mod because that would be most of the game and its already a golden rule to backup all files and folders before installing any mods, if you don't like something in a mod then all i suggest is to learn how to change it or ask the person nicely and then might do something for you or already have released a fix for it.
Also which mod are you playing?
