Meaning: 'Virtue' refers to a behavior showing high moral standards, indicating that non-violence is not just a means but a fundamental quality.

Wrong options:

• value: 'Value' suggests worth or importance but does not capture the moral quality that 'virtue' conveys in this context.
• cost: 'Cost' implies a price or sacrifice, which does not align with the positive connotation of non-violence as a moral principle.
• goal: 'Goal' indicates an objective or aim, which does not fit the context of describing a quality or essence.

Correct answer: evil

Meaning: 'Evil' refers to morally wrong actions or behaviors, emphasizing the need for love and care despite such actions.

Wrong options:
