I doubt that. Like RDJ's Tony Stark balances responsibilities and hubris yet Thanos is clearly his arch-enemy.
In the comics, Tony Stark hasn't always had a consistent and clearly defined personality, i.e. the idea between responsibility and hubris. David Michelinie wrote Tony Stark as a self-destructive rich alcoholic, not a futurist dude. Even then Justin Hammer was his arch-enemy. Warren Ellis introduced the idea of Tony as this futurist, and yeah Tony in Extremis doesn't need an arch-enemy, but Millar took the futurist Tony under his wing in CIVIL WAR and made Cap his Arch-Enemy which continued until Hickman's New Avengers where Time Runs Out ends with Tony and Cap duking it out while the final incursion hits.
