The starting point of my argument is that you don't want to download for yourself i.e. there's nothing out there that you want. For whatever reason, it's an hypothesis --a very likely one since millions of people don't use torrents, *raises hand*, *all his family members raise hands*. The hypothesis can't be disproven because it's not a conclusion, it's the starting point.
So, provided that person X doesn't want anything from the torrent network, if it was empathy his main motivation as you say, he might still install a torrent client and download things he doesn't want and will never use but that he knows people want, and just seed all the time. Since that never happens, my point.
