I don't think so. However, we need to have choice to truly do good. Why else would there have been a forbidden tree in the garden of Eden. So, we don't need to see evil, we just have to have the option of choosing it.
its a bond between people that goes beyond just a fiendship, its when you are happy every time you see them and you are willing o go out on a limb for them and ou want to make them happy. thats my opinion
