Regardless what the final objective of magical girls truly is, fact is that Mami fought with the mentality of "Hero of Justice" in mind. Fact is that it actually worked for her, even for a longer time than Kyouko acting selfishly. Fact is she saved and prevented the death of tons of people by protecting them from witches and familiars alike. Because of all this, Kyubey says she was an isolated case, that the rest of magical girls aren't nor act in the way she did.
The truth doesn't demean at all from her own approach, mentality, intention, sacrifice and deeds she followed, embraced and accomplished during all that time.
