He will not take others word for it, he must continue the quest until the very end.

I think this is the way. But let me offer some words, lol.

To paraphrase a book I read about the (French?) philosopher Spinoza's thought: every particle of the universe is necessary for the Whole to exist, and the Whole is God. So to be against any aspect of our manifestation, or to judge it as wrong, is to be against God and against Life itself.

Essentially Spinoza thought this was the path to peace and joy. Total acceptance of what is. Including enslavement and power abusing structures. These things are necessary for the existence of dew on the flower, the passion between lovers, the color in our sunsets.

Of course, acceptance does not mean that one has to be involved in these 'evils'. But acceptance could free one to be totally involved with the simple hedonism you describe.

And what happens when the majority of humanity lets evil be, and dives into passion and beauty? Is that the path to actually creating a world where 'evils' do not exist? Based on the analogy/idea that the wolf you feed is the one that thrives?

Or are we doomed by the nature of our minds to divide the world into dualities of right and wrong, to judge some things as good and some as bad, regardless of the world we create?

I do think that right/wrong is subjective. It is only our human mind that imposes that duality. Objectively speaking, things just are, neither good nor bad.

Love is God and God is One. In that total acceptance, that embrace, that love, of All that exist is peace and joy, and in that peace and joy resides the transformative, creative power to actually accomplish what we seek to accomplish by ridding the world of evil.

And perhaps all we need to transform is our own mind. God said 'let there be light' and there was light. All we need to do is say 'it is good' and it will be.
