What about the people who didn't ash out but died for other reasons due to the ashing out?
Your having open heart surgery when your surgical team ashes and you die on the table because of it.
Your a pedestrian legally crossing in crosswalk when the driver of a car ashes out so the car now out of control runs you down and kills you.
You were on one of those planes but the pilots ashed out and the plane crashed.
Countless such examples. Did Tony bring all them back too or do they stay dead since their deaths came later after the snap.
