Is not the true root of evil typically man-derived greed?
For example, money is the root of all evil. Well... the greed for money hoarding is a man-made concept, affecting mostly those that barely have any. Hence, the conception of "root" and "evil" are ideological concepts that develop as the few acquire more and the many may only acquire what's left to them.
Much education is typically indoctrination, or dogma, without much focus on conceptual, independent, and/or cultivative thought processes that examine, investigate, analyze, and/or critically think. Once many people start to "wake up" and get a taste of thinking for themselves, then the actual roots of any evils will become quite clear and not a constant meme of old.
