In terms of the Grand Scheme/Big Picture....you're right. There ARE no winners in war...only losers. But that is a perspective that only avails itself to the very wise and-or spiritually mature. Most other beings are too caught up in the social drama...the scramble for resources, mates and status....to see that. So they fall for illusion that taking from others is a "plus" to their "column". But that gets us back to what the definition of "evil" or (its lesser cousin Sin/Spiritual Poisons) is. In the Jude-Christian tradition it can probably be best categorized as "Malicious self-interest" or "Malignant Narcissism". I think the Vedic/Buddhist tradition does a better job of defining it. Greed. Hatred....and the Illusion (ignorance) of "Seperateness" An "I" or "me" that is hard and enduring entitity sperate from the circumstances in which I exist.
