If Evil doesn’t exist then we are robots….Then we don’t…

If Evil doesn’t exist then we are robots….Then we don’t need feelings…..
Pain can be sweet…
What is Utopia without Evil….
Utopia will become hackneyed, boring and insipid with time as long as we are made feeling being….we will long for a spice of stress or pain or challenge…. Utopia itself will become evil with time.
I do not think a feeling being is callable of Utopia even if evil ( stress, gloom, failure) is impossible
