I think there is a complicated side effect to overcoming evil in that we are forever changed by it. I think after we ingest some of the cruelty of the world, it takes years off of our lives, but it also gives us wisdom and a little grace, hopefully a sense of compassion.
Because the existing education system is oriented towards materialistic goals we need to pay special attention to inner values such as tolerance, forgiveness, love and compassion.
Apart from selfish reasons, such as fear of punishments, fear of blame, of dishonour, etc, there remains only two motives that can stop (or prevent, "empâecher", Fr.) men from acting badly; the natural sense of commiseration (or "sympathy", - "commisération", Fr.) for one's fellow men - compassion, and the influence of education, by association of ideas ("par l'association d'idées", Fr.) - habit.
The perspective of Love doesn't leave anybody out. Until your vision and compassion is big enough to include those who oppose you, you are simply contributing to the continuation of destructiveness . The end of separation is the salvation for all.
If one doth act in friendly wise, With no evil thought toward any single creature, And in so doing becometh proper, And if he have compassion in his soul Toward all living beings--this noble one Doth acquire abundant Virtue.
As human beings we each have a responsibility to care for humanity. Expressing concern for others brings inner strength and deep satisfaction. As social animals, human beings need friendship, but friendship doesn't come from wealth and power, but from showing compassion and concern for others.
The indifference, callousness and contempt that so many people exhibit toward animals is evil first because it results in great suffering in animals, and second because it results in an incalculably great impoverishment of the human spirit.
Understand the suffering of worldly existence.
Abandon its causes of ignorance and selfishness.
Practice the path of meditation and compassion.
Awaken from suffering within Great Peace.
