but honestly, the worst thing about Tony losing JARVIS in AOU is that he never expected it to happen. People? sure. He’s always waiting for them to leave, willingly or not. But his bots? They’re the closest thing to children he has and they’re not human. They’re made of metal and circuits, stuff that just doesn’t degrade. 

They were never supposed to die. Especially JARVIS, who doesn’t even have a physical body to break. He can just up and move his code if needed. 

Tony built them to outlast him, to live to see the future and things that he’d never be able to see, he’d built them to be his legacy and he was always comforted by them because they’d never leave him.

Except JARVIS died, was killed, ripped apart in front of him and no one seemed to care. 

And if you think that Tony doesn’t blame himself for JARVIS’s death you are so wrong.
