The entire motivation of the bad guy in Madame Web is that he saw the heroes killing him in a dream so he wants to kill them first...

The only reason they want to kill him is because he keeps fucking attacking them...

That movie is so fucking stupid

I haven’t seen it, but that’s like, most Ancient Greek stories about prophecy. The only reason the prophecy comes true is that people take actions to prevent it.

For example, Oedipus’s parents find out he’s gonna kill his father and marry his mother. So when he’s an infant they nail his feet together and throw him out of the city. He’s taken in by some kind people, eventually makes his way back to the city later in life, kills his father in an altercation without knowing it’s his father, marries his mother not knowing she’s his mother. If his parents had never heard the prophecy and just, you know, raised him, he wouldn’t have done those things.
