Layla Miller once reflected that Doom is incapable of accepting that he himself might be the reason for his failures. This is most keenly reflected in Doom's continued refusal to accept responsibility for the accident that fully scarred his face, instead preferring to blame Reed Richards for sabotaging his experiment. While his high opinion of himself is generally accurate, he is unable to accept when others may have a better understanding of a situation than he does, with the occasional exception of hearing the recommendations of heroes such as Mister Fantastic or the Thing when it is to his advantage. Even when teaming up with others against a greater threat, Doom will often try to subvert the alliance for personal gain; for instance, while allied with Adam Warlock and other heroes against the Titan Thanos, he attempted to steal Thanos’ Infinity Gauntlet before its owner had been defeated, potentially disrupting Warlock's own plan to defeat Thanos.
