It's All About Me

Fry: Bender, this has nothing to do with you!
Bender: That's impossible!

Ah, the Ego.

The part of the psyche that defines you as an individual, and considers itself (read: you) a separate entity from the rest of nature and even the entire cosmos. Perhaps advantageous now and then, and even necessary for survival in some evolutionary bygone, in modern times it leads to downright embarrassing behavior.

Having a big ego is not the same thing as an overinflated one. The Greeks examined this false dichotomy in their stories dealing with honour and hubris, and Bill Shakespeare wrote a play about it called Titus Andronicus (in which the major players all suffer from this condition). Freud termed them the Ego and Superego.

A healthy ego exults the strengths of an individual in an overt way, which—on balance—can benefit everyone. An unchecked ego, however, is mainly preoccupied with blocking out "unacceptable" thoughts that are hurtful or belittling to itself, even tuning out the entire world if necessary. Toddlers have this attitude by default, as their brains are not developed enough to understand that other people have different viewpoints. We're less forgiving of (non-disabled) adults who behave this way, also termed assholes.

Warning: The limits to which the human ego can expand have not yet been reached.

When the cause of the attitude is being raised in a family of great power and wealth, you have a case of the subtrope Royal Brat. For religious cases, see Egocentrically Religious. Overlaps with Moral Myopia when debating the rights of others versus the rights of oneself. When combined with a massive sense of self-preservation, we get the Dirty Coward.

See Narcissistic Personality Disorder and Anti-Social Personality Disorder for when it veers into villainous territory. Also commonly related, both in-universe and otherwise, to Muse Abuse.
