Just because it wasn't mentioned doesn't mean that she didn't think it, though it would have been interesting to see how she would address that.
I think it was more out of an act of kindness. Even if she does get revived, she still has the memories of being killed, and she knows the system of MS and witches. She'll just be needlessly worried. And that's if she doesn't come back as a MS. If she does come back as a MS, she has the life-risking duty given back to her once again, which more or less defeats the purpose of bringing her back to life anyway.
The main reason is probably that Madoka did not [at the time] wish to be a MS. Her feelings toward not wanting to be a MS also extended to other people, as when she showed concern when
became one. The reason being that, once again, it's dangerous. And that fact was bluntly proven to her when
. Bringing her back to life to make her face that kind of life again would be almost cruel. Yes, even if Madoka is now a MS too. If Mami retains her MS status, then it'll just create a weird tension between them. It wont be mentioned by either of them, but it would be there. If Madoka were to wish that she be brought to life without her MS memories, then she still loses in the long run when WN appears and
. Besides, even if she does come back, she'd still be anti-entropy fodder for QB as you'd assume she'd still be a MS candidate.
(Well, the musings of a bored individual whom should be sleeping by now for school tomorrow.)
But rather than that, I'm wondering as to why in the hell Kamijou had never considered the idea of playing the violin by using his right hand instead. His right hand seems perfectly fine, so all he has to do is get used to playing the notes with his right hand and controlling the bow with his left. If he can't grab the bow, then somehow tape it on. BE INNOVATIVE. From a critical perspective, people who make great comebacks always get even more attention and widespread fame than they did before they got into their life altering accidents. He apparently already had a prodigy level of musical sense and talent, all that required was a little adjustment.
In fact, if he did manage to do this, I'd imagine that half the stuff going on in this show could have been averted.
! First of all, if he did restart playing the violin, then Sayaka would bring more CD's and stuff to get him motivated, and they could have possibly gotten into a decent relationship. This removes Sayaka's wish, and averts her becoming a MS. Then Kyouko wouldn't have [prematurely] died, and Homura wouldn't despair after showing too much of her time powers (Remember, Homura stops time and shoots QB when Madoka is about to wish to help Sayaka, but that wouldn't happen if Sayaka doesn't turn into a MS. This then leads to QB [probably] not figuring out what Homura's powers are, and making the connection between that and Madoka's enormous fate, which in turn leads to QB not telling Homura about this and causing her to despair).
However, QB would most likely not keep away from these two even if they continue to not make a wish after Mami dies, especially Madoka. So he'd probably start scattering GS's all over the place, trying to create a situation for them to wish in. This'll probably eventually cause them to run into Kyouko, since this territory is technically first come first serve. Depending on how things go, Kyouko would likely become friends with them(with possible yuri with Sayaka except this time, it's a good end. With the additional benefit of Kyousuke getting Hitomi as well). Because Kyouko doesn't die with Oktavia, and it's hinted that it is possible to stop WN with just the 2 of them(Kyouko and Homura), it's possible that they actually end up killing WN. Since there's no opportunity for QB to explain the SG gimmick, the girls would remain relatively ok about being/becoming MSs. If WN isn't defeated, then there's two more wishes available in Madoka and Sayaka. Which will probably end up being wishes like the power to kill any witch, to fix all the damage caused by WN(after killing it), or something like that. The best part is since Homura doesn't despair, she can rewind time again.
So is it just me or is Kyousuke behind much of everything as much as QB is?
