Evil is endemic in the world. To claim otherwise is naive. People are careless to evil influences around them and without protection they become subject to being agents of evil themselves.
Proactive non-resistance to evil is a means of combating injustice through active love. When applied in the context of social or political affairs, this may include the practice of satyagraha as advocated by Gandhi, namely a combination of truth and firmness, or steadfastness to truth. This is not to be confused with passive resistance which fails to reject violence as a matter of principle. Non-resistance to evil aims to convert the other by patience, honesty, sympathy or self-suffering, based on a belief in the inherent goodness of every human being.
