I’m finally getting a sense of what Iron Man is objecting to, in regards to Ulysses’s power to predict the future. It’s all well and good when you get an advance notice about an impending disaster, or rampage from a super-villain. But what if he tells you that a former criminal that you gave a second chance is going to revert back to his ways? How do you deal with that? And now armed with that information, would any of your actions now would subtly shape this future into existence? What if the very act of telling Spider-man that Clash is going to revert back to his villain ways makes Spider-man do something that causes this in the end?
In a nutshell, I feel like the argument boils down to what if you’re told of a future that you don’t like.
