So, guys, last time I've seen a madoka magica thread you were talking about a theory that Madoka's wish may be the thing that will cause the apocalypse and that Homura may know it (being a time traveler or not), so she's doing everything to not let Madoka make a wish.
So here's my question: why she don't kill madoka? She tried to kill QB so I guess that she can kill a human too. And please don't say that it's because she loves madoka.
