If Tony died in Siberia, no one would Avenge him
Apparently there's a story out there that showcases how disturbed prop-Tony fics can be. It has Pepper and Happy, folks from Shield, Clint's family, the Asgardians, the Parkers, Red Room agents, and DC heroes and villains. What brings these folks together? Allegedly to avenge Tony Stark's death in Siberia. Apparently even the heroes of these universes think it's perfectly okay to punish people who weren't even IN Siberia, and it's okay to make the punishments eternal torture. Natasha is trapped in the Red Room, Clint re-experiences childhood abuse, Steve is assaulted and has an asthma attack, Wanda relives her family's deaths by Stark's bomb, Scott and Sam are killed in circumstances to do with their suits. Plus the torture is broadcast like entertainment, because this prop-Tony writer thinks the America viewing public are sadists.
So where to begin? First off, the DC folks would never have heard of Tony Stark. None of these other folks are sadistic. They would not be okay with torturing anyone, or broadcasting it. That's what VILLAINS do. But most importantly, Tony Stark's death wouldn't be avenged because he either died from 1) being too stupid to call for a ride home, or 2) refusing to stop attacking Bucky and Steve even after Stark cut off Bucky's arm, shot Bucky in the back, and kicked Bucky in the head with a powered, armored boot. If Steve had to use lethal force to stop Stark's rampage, it would be self-defense or justifiable homicide in defense of others. There's nothing to avenge.

Pepper looked grim as she, Happy, and Rhodey watched the end of the Siberia fight in Rhodey's hospital room. Tony again launched himself at Sergeant Barnes. Captain Rogers again intercepted and prevented Barnes from being further injured. Finally, Rogers destroyed the main arc reactor.
She saw the mini backup reactors light up as Tony yelled after the Captain as the Captain helped his wounded friend to stand. She nodded as the Captain shrugged and dropped the shield.
Then she watched as Tony focused all of the power left in the suit to one of the repulsor gloves. He fired at Barnes' back AGAIN. But Rogers pulled Barnes out of the way as they both fell through an archway. Tony's shot landed on some panel. When it exploded, it caused some chain reaction that resulted in the ceiling collapsing.
The feed stopped before the tons of concrete buried Tony.
Maria Hill deactivated the screen and said, "I'm very sorry for your loss. But I hope this shows why we will be taking no action against Captain Rogers or Sergeant Barnes."
Pepper nodded and said, "It's clear that Captain Rogers was trying to prevent Tony from attacking Sergeant Barnes. Even after the Captain disabled the Iron Man suit, Tony still lashed out against them. He was clearly going to shoot Sergeant Barnes in the back."
"Again," Happy pointed out with a nod. Then he said, "I'm the last person to bad-mouth the boss, but he was out of line. That guy was literally unarmed and STILL Tony was attacking him."
Rhodey sighed and sat back in his hospital bed. He said, "I knew there was something hinky going on when Tony sprang that new guy on us at the airport. But I never suspected he was that far gone."
Pepper looked at Maria and said, "If you are in contact with the captain and sergeant, please let them know that we understand...they did what they had to do to survive."
Maria nodded and said, "I'm sure they'll appreciate hearing that." Maria hoped Natasha, Phil, and his team would offer Steve some comfort as they assisted him in breaking the other Avengers from the Raft. It was a bad situation, but Steve should know no one was going to blame anyone for Tony's death except the responsible party: Tony.
