I think that's not what is happening.
Ahmed knows he's lifting from Spidey, so he won't lean into the trappings of it.
Her father won't be her Uncle Ben and I don’t think he will die.
I believe what's happening is Strange will try to trigger a successful terrigenesis.
He says that his Inhuman genes are what's killing him because he has the equivalent of an autoimmune disease as part of him tries to go through terrigenesis, while the rest fights back.
But he says that the Inhuman factor may also be what saves him. So he likely does not plan to excise the genetic civil war, but to end it. And that only happens when Mr. Khan dies, or when he undergoes the transformation.
So her father may end up blue or otherwise oddly shaped very soon.
Which is far more interesting than being dead.
For one it could explore how conservative Islam, namely Aamir, handles a believer who is no longer fully human.
Or how the family dynamic changes now.
A visible mutation would mean social stigma, maybe an identity crisis.
And how does Kamala react to this?
And if they lift from the best Spidey stories, that's still a new spin on a good formula.
Which is far better than "quirky genius girl power" and acting like you just invented the wheel.
