Nope. Good Ends are any ending where the Devil is dead and where you and the people you care about are safe and happy. If you care about all the Meguca then a good end is where no one dies. You currently only care about Madoka but you're starting to warm up a little to Mami and Sayaka.
The True End is much more complicated than that.
I might have explained it badly, but that's basically what I meant. At least one person dies, even if it's just the main villain (Devil).
