>>2749096>Sayaka asked Madoka to keep her witch form because by doing this her wish will exist forever.Sayaka didn't ask Madoka that. Madoka said that the only way to keep her wish intact meant that Sayaka would be taken away by her. Sayaka says that she wouldn't have it any other way. They both agree that the wishes of magical girls are worth the sacrifice.
>When a magical girl is purified her wish goes away too.Incorrect. You need to watch the series again. It is specifically stated that Madoka cannot undo the wishes of the magical girls without causing humanity to revert back to cavemen. Madoka does not undo any magical girl's wish, ever. Except maybe Homura's by not existing any more.
But really, at least post some Nagisas. You can find something on google in 3 seconds.
