I think it would cause you more problems to take this fish than to just leave it and forget about it. Your compassion is understandable, but these sorts of things are quite common and unless you're willing to tackle the housing issue 100% and not half assed i don't think its worth it.
I remeber a thread a while ago about someone warning others not to take fish just because they felt bad for them. I think it was about a guy who bought some mistreated bettas from some place and ended up spending more money on meds trying to fix them and then they eventually died. He was a little choked.
