I know that Thanos threatened Mephisto and he took steps to ensure that the future he went to would not happen but does anyone else think it'd be funny if everything Thanos has done to prevent his future self from existing instead guaranteed it? I mean I think Mephisto didn't even know about Frank Castle before Thanos mentioned him. So maybe Thanos is unintentionally creating the future he went to. I think that would be a good twist with everything that's happening with Thanos.
