Ole Anderson: Heroic Fatalism or Bi-Polar Case Study?

The Swede Ole Anderson in Hemingway's "The Killers," is described by some as heroic and noble for accepting the end of his road in stoic fashion. For me though, the story seems open to other interpretations.
I genuinely don't know very much about Ernest Hemingway accept that despite a life lived on a very grand scale, he struggled with serious depression. When I read the scene of Anderson and Nick Adams him in the boarding room, I immediately visualized a very melancholy man, a man who would not leave his bed for any circumstances, including imminent death. A man who despite others caring about his own well being he did not. The behavior seemed like that of someone who today would be diagnosed clinically depressed. Today depression is recognized and treated professionally. For Hemingway, treatment consisted of a life with intense highs and crashing lows, fueled by raging alcoholism in Hemingway's case.
My point is, can this story be related to Ernest Hemingway's struggle? The Swede is a boxer, an archetype of physical fitness. Ernest Hemingway was a larger than life fellow who seemed to live every day as an adventure. Could either of these men show weakness by 1920's culture? Could Hemingway be describing one of his depressions; to stay in bed all day trying to decide to get out or not? To not even care if men are coming to kill you? This story gives so many details about the moment, without giving hardly any detail about the characters background.
The story is so short that when it's remakes came out in the 40's and 60's, the back story to this setting changes drastically. The film noir with Burt Lancaster shows The Swede as a boxer who was double crossed by some dame to steal and kill from the mob. The 60's version has Lee Marvin wanting to know what makes a race car driver face his end so valiantly. The versions very in several ways accept that the man who dies is courageous and didn't seem to deserve what was coming,why? Hemingway only gives an account of The Swede's last night, who's to say he didn't have it coming? If the story Hemingway wrote about a time and place can be expanded into a larger story, then that story can be expanded into anything. Maybe hit men have come to kill him for abducting a bus load of children and raping them senselessly. Maybe The Swede did suffer from bi-polar disorder. And if these hit men would have shown up two days earlier or two days later than they did, who's to say The Swede might not have trapped them in his boarding house and burned it to the ground. Maybe Ole Anderson was a lonely depressed hermit, who imagined people at a diner interested in him enough to want to kill or warn him.
I liked the story for the fact that its realness left a lot of details to be undisclosed. The whole story, any story is never totally there. Maybe The Swede was a noble guy who got mixed up with mobsters, maybe he was a child raping murderer, maybe it was just Ernest Hemingway on a low day, waiting fro someone to someone to show up and do him in so he doesn't have to go to the effort.
