The root of all evil is this thing called ego.
I don't buy this. It sounds like unbalanced pop-psychology to me.
There are plenty good things that come from a healthy ego.
Ego helps young adults strive for independence.
Ego can help people fight back when being abused or bullshitted.
Ego motivates a lot of the individual achievements that make the whole human species so amazing in science, sport, arts, politics, and business. Try running a sales team full of people low on ego
You can train people to listen and respond to customers, but without strong ego they won't negotiate effectively and have trouble bouncing back from rejection. On the cutting edge of vital research - what could we expect from a research team whose leader doesn't yearn to be the first to publish

Yes there are negative (evil) aspects to ego, not the least of which is religious know-it-alls whose primary hope to satisfy their hunger for respect is spruiking 'personal insights'
into the thinking and ways of invisible deities – prophets, clergy and apologists parasiting off the imaginary glory and powers of the mysterious invisible and unverifiable, all for their own little slice of ego-heaven right here on this earth.
