She was nice wish made for her father started defending people. After her father found out killed himself and family she stopped being nice or more had no reason to as it would end badly. The only reason you would say she was not nice is that she did not place value on the lives of others strange as it might see I don't think that makes her not nice, i mean i don't feel bad when I eat chicken but i would feel bad if my pideons died kind thing with her. When she meets and is unable to kill Sayaka, then forced to look at a refection of her past self in a sense. She tries to help with advice doesn't work, she then stops the suffering of Sayaka and goes with. Pretty nice all things considered

She indecisive and shy to feeling knows what she wants wont take the step to accomplish. Makes wish based on her present feelings and beliefs(good and bad) Has a emotional girl break down problem being she is not a normal girl cause the breakdown to not get washed away with time but turn into a murderous sword weilding monstrosity (tuff cookies). In other time lines that we saw she was unaccepting to Houmra and Kyouko but she never last long as she does go witch each time. Later one she did befriend Kyouko still died. So she was not overly mean or stupid just a schoolgirl in unprecedented situation. So basically i agree with you on Sayaka for the most part.

She did not buy into QBs line she had no choice it was wish or death. She was already shook up from the crash so there is no right or wrong on how she got started just unfortunate circumstances. I would not call it strong or weak her actions after finding out the witch thing. One side yes stop them before they become witches yes is a method kinda like kill before they become a zombie thing. That is one side on the other she never thought maybe there was a way to stop this yes she was stress and just saw Sayaka become a witch and get killed, but magic.possibilities.ENDLESS. She does not react well when faced with sudden changes, sounds harsh but i say it as she was a veteran magical girl and playing the calm collected card.

Honestly I do agree with Homura abit. From what I see of Madoka unless it is for the sake of other she will do nothing and when she does she does it to the end, but aside from that she is a simple girl easily influenced and lead on by others like how she became a magical girl in original loops to save a cat, for cake and to help Mami. If she knew she could have created that afterlife and rid world of witches thing i am pretty sure she would have tried it from the first loop if she new all the details. Considering in final loop she really did not get told anything aside from what she saw her not becoming a magical girl is rather acceptable to me.

risked her life and ultimately sacrificed it in the end to try to bring back Sayaka and then joined her in the afterlife once she knew she couldn't. That's what makes her deemed as nice. Who cares if she lets other people become grief seeds? Homura herself semi-willingly let some of the girls died when she knew it was hopeless and instead focused more on saving Madoka above all else. Why else didn't she simply went on ahead and killed Charlotte before Mami died? Because she was more focused on preventing Madoka from becoming involved and end up being a magical girl. Therefore Homura's priority was not to save everyone, but more of Madoka. So in all honesty, she and Kyouko have a lot in common in terms of strong constitution, exp, mentality, and level of power. Which is why they are always envisioned to be teaming up together and be the last ones standing against the Walpurgis Night in the PSP game and many fanarts (Madoka is a toss-up between being on the sideline or being killed (?))

She auto-distrusted Homura without ever giving her the benefit of the doubt. Even in the original timeline, Sayaka looked down upon her when she was Moemura, unwilling to trust in her abilities. So there was already initial friction between those two at the start. And in all timelines, she always turned into a witch due to her obsession with Kamijyou, which is why she joined Madoka to the afterlife even in the final timeline. So nothing wrong there.

couldn't simply handle the truth and broke down. Simple as that. Hell, I bet you anything that she would've still reached that same conclusion, even if she heard straight from the horse's mouth. Because she was the closest to QB out of any of the girls and clinged on to his every words, most likely due to her loneliness. She was the staple magical girl that constantly relies and believes in their magical familiar ally, even though that was supposed to be Madoka's job. Supposedly there are statements in the 3rd movie and what all of her fans trying to advocate is that, if Mami had all of her friends and their constant support, she most likely wouldn't have broken down like that. But who knows. At this point, it's all theory-crafting and "what ifs" for that one.

That was more for Homura keep on trying to make Madoka do anything so that she won't become a witch again.

But if you REALLY wanna get technical and into it, then so be it.

No matter which world it was, she kept on turning into a witch and Homura kept on resetting. So therefore Madoka's help always turned into something worse, especially she eventually grew into becoming to the most powerful witch in existence. It was stated by QB that Homura could've had a chance to beat Walpurgis even if she just had Kyouko's help, which is why QB intervened in their plannings. So therefore Madoka's "high potential" was never really needed. And as for her final wish, she may have removed the witches from being born from magical girls, but however, that in turn gave rise to new threats, the wraiths. So in the end, she didn't achieve too much. Also, after the said final wish, it in turn made Homura fall into despair, turned into Devilmura, and "reset" the world as how she want it to be. So in the end, Madoka pretty much accomplished nothing, but simply giving up one evil for another.

I actually don't think Rebellion changed Homuras character all that much. We were made to think Madoka saved the world in the first season but the reality is the possibility of harvesting grief seeds still existed, it was just that the incubators tech was directed to wraiths instead. It was another corrupted wish, while magical girls were no longer harvested in this world, it didn't mean magical girls couldn't be harvested. What set the events in rebellion in motion was Homura telling Kyuubey her story at the end of season one, thinking he was now a good guy. Which is why he says hesitatingly, that if grief seeds were to be found, they would use that over wraiths due to higher efficiency. Which brings it back to where the incubators were trying to take Godokas powers. If they did that, they would rule over all of the universe (time and space) meaning no way to stop the incubators. Homura hit the self destruct button to protect everyone by stealing madokas powers so the incubators could not take it. In order to keep the incubators from taking Homuras greif seed, she made herself into the "devil" a witch so powerful and far reaching that she could function for a while without degrading and giving the incubators an opportunity to harvest her. However, her final lines in the movie shows her despair as she knows this is a temporary fix, but with Godokas failure she no longer knows who to rely on and how to make the problem better. Homuras transformation to devil was a logical and not radical decision. Homura is the one always trying to fix the problem because she is the only one who knows the big picture, but unfortunately the task is always bigger than she can handle.
