The fact is that we can recognise the evils in this world, and that we can differentiate between good and bad - not only within this world but within ourselves.
Equally factual, though, is that different people in different places (and different times) classify actions differently: to me, stoning a women for adultery is wrong, for other people in other places it's a moral requirement.
We recocogise that none of us are perfect, and this world is not perfect. We know there can be something better.
How is this world not perfect? Our behaviour I'd agree isn't ideal, but the world as a construct? It is what it is.
This scenario is surely not what you would expect from an evolutionary process which moulded us into the reality which exists on this earth.
You don't 'expect' anything from evolutionary processes, they are not predictive. You simply observe what results and try to determine in what way particular traits either give a direct advantage or are evolutionarily-neutral byproducts of otherwise advantageous traits.
Unlike the other animals, we do not just accept this reality. Humans have a vision of perfection.
And that sort of abstraction appears to be a byproduct of our advanced linguistic and tool-wielding capacities, which emerged as it granted us survival benefits as a social creature able to co-ordinate and defend ourselves.
Jesus shows us how we can achieve this perfection.
No, the allegation of Jesus asserts that we can't achieve this perfection, but that somewhere else, somewhen else, someone else has and will take us there...
