From Captain America and the Mighty Avengers #1
Some context
Steve Ditko was famously a follower of Objectivism, a philosophy devised by writer Ayn Rand (her hit novel, Atlas Shrugged, starred her perfect ideal of an Objectivist hero, John Galt). His following of those beliefs sometimes affected the Spider-Man stories that he plotted (originally with Stan Lee and then by himself alone) before he left Marvel.
Without Uncle Ben's sacrifice, he would have been a dickhole.
Good thing Miles didn't need that event to be a hero, we are up to the neck of corpses in here.
