Miles Morales, Kingpin, and Miguel O’Hara are all such interesting foils of each other. All three experience loss and grieve with alternative methods.
Kingpin refuses to accept the reality of his loss while still being aware that he caused his family’s death. In his refusal, he attempts to rip space and time apart, not caring about the consequences of ripping them from another world. He wants a redo, however, Fisk does not ultimately learn from their deaths, he continues on his path of crime using their demise as justification rather than a cause for change. Fisk is blinded by a simple goal of having his wife and child back, yet does not consider whether they would want to be with him knowing the crimes he has committed.
Miguel does the inverse, he places himself into a new world to live out a happier version of his life - one that does not ultimately belong in. He ends up causing the destruction of that world, paying the ultimate price for his selfishness. He takes this lesson to heart with the additive that all Spider-man must suffer. Miguel never conceived the idea that he could create his own happiness in his universe. He learns from his trauma but does not see a way to work past it.
Miles has the chances to alter what might happen, the death of his father, and wants to jump at the opportunity. He is not asking for a redo (like Kingpin) or a restart (Miguel), instead he simply wants to give everything he has in attempts to free his father. Why just let something horrible happen if it is not clear it has to? As Gwen discovers, the death of a captain can be interpreted many ways in the canon (her dad quits, aka his career as captain is dead). Why not try to save him, where is the harm in that? Miles might not have meant to be Spiderman in his universe, but that doesn’t mean he should disengage from the role entirely.
