Aristotle quote highlighted the significance of self-central in face of utilisation of power.

As it is said, 'If you want to test a man's character, give him power.' It reflect how a man is able to utilise that power - for virtue or for vice. Our actions of doing something or doing nothing, are within our control. At few places, it becomes dharma to act eg to voice against exploitation, & injustice. In some situations, one need inaction also eg patience to avoid conflict escalation. So, one must discern wisely to act or not to act. One must act to ensure greater good. Hitler used his power to inflict injuries and ushered disaster on humanity.

On the other hand, Mandela used his power to voice against apartheid and exploitation. This difference in actions is carried by our virtues like compassion, justice, integrity, love towards humanity and courage. Socrates chose to sacrifice his life than bowing before instant might. On the other hand there were cowards like Omi Chand who sold country for their interest and kept killing millions. The power of restraint and power utilisation for greater cause can save humanity from wars and theft ensuring conditions where justice prevail, fulfilling mandate of UN charter.
