I remember hearing something about how the suits AI would keep fighting till the battle was over if he dies inside the suit. I don't remember where I heard this, I think it was one of those marvel pages on insta.
My late Dad used to have a saying about not going into business with family, but it applies to the constant reanimation of charachters so that the franchise can keep churning out more movies :
"Blood might be thicker than water - but not as thick as a dollar bill."
Nothing he dies in the suit.
Nothing like that has ever happened.
If that happens he gets brought back to life in the next episode.
