In the sense that "ego" is understood in both psychology and spiritual circles, low egotism is associated with the qualities you describe.

High egotism -> high conscious opinion of one's self (compensating for low subconscious self-worth), need for external affirmation of self-worth, and propensity for aggression and meanness in the pursuit of that affirmation.

Low egotism -> content with self-worth, unreactive to external criticism or praise, willingness to do what is "for the greater good" regardless of short term challenges and resistance, trusting one's self to achieve the best outcome in the end.
