More often, even the sickest most evil seeming people have some reason, no matter how insignificant, for becoming the way they are today. Like kids killing off their step siblings because they were neglected, or a young woman helping to abuse and kill another woman because she loves her boyfriend. People don't always need big reasons, or even reasons that make sense to do the screwed up things that they do. The point is, that they almost always HAVE a reason.
Orochimaru hasn't been redeemed, and I doubt he is ever going to be - despite his backstory about doing what he did because his parents died. Orochimaru moved past that.
Danzo was never redeemed, even if he wasn't evil in the truest sense.
Hidan, Kakuzu, Deidara, Zetsu, Sasori, Kisame - none of them were ever redeemed, despite their respective backstories - they died ('cept Zetsu) evil, unchanging in their views and beliefs. Neither has Kabuto been redeemed, despite his backstory - he's just stuck in Itachi's genjutsu still.
So did the Sound 3 and Sound 4.
On the other hand, Kurama, Konan, and Nagato have been redeemed (plus Gaara and Neji, but they were never really villains, imo), and Sasuke redemption is inevitable as well. Itachi was never redeemed, as he was good to begin with.
So Tobi being redeemed wouldn't surprise me, or disappoint me, at all - he's far too much like Nagato. I do believe that he's going to die in the process though, perhaps saving Kakashi.
I think Madara would make a perfect final villain for the characters to face off against - sure, he hasn't been alive long, but he was introduced into the story a long while back, and he seems truly uncaring, unhesitating, unrepentant. He may be the one with no sad back story - perhaps he is just the one that wants to see the world destroyed - not saved like Tobi in his twisted way. Especially if Madara manipulated or twisted Tobi's thinking to begin with.
If people want to be frustrated with the status quo of the villains and the whole redemption thing, than that's fine and I respect their opinions. I just don't see what the big deal is myself personally.
