>>8787>>8788>> "the road to hell is paved with good intentions"
In my opinion it's a bit debatable.
On the one hand that concept was never explicitly stated in any of the dialogue (that I can recall, anyway).
On the other hand, I'm not sure it needs to be. It certainly seems to match a lot of the plot elements, even in the original TV series. You might say that every magical girl's story follows that to some extent: they make their contract with good intentions only to fall as a direct consequence of that contract, so I don't think it's inappropriate to say that PMMM has that theme.
Even in the case of Sayaka's wish I think the intentions are good. In her discussion with Mami there are two options considered, and I'd say that both are good intentions:
Either she means to selflessly heal someone else with no reward in sight, or she wants to fight for justice & maybe pickup a boyfriend along the way. While the latter might be somewhat selfish, I'd still say the intention is good.
