I guess the counter would be that the captain was always "fated" to die at that time, and if The Spot didn't show up something else would instead, but like, if the timeline is that flexible can't it just give the captain a heart attack?
I didn't dwell on that one too much. Sure, the vision was of him getting crushed under a building but that was only cause by Spot. Argument is that he still would have died at that time regardless, as as a rule of rhumb the "Captain" always dies in the line of duty from what I remember. So I don't think a heart attack would have cut it.
