Is It Possible That Being Is Consisting Such That Evil Exists?

Why is it that being is constituted such that evil is allowed to exist? It's ivan kramazov's a, what critique of of alyosha's a christianity assenti. And i wonderif one could recast it as the need for otherness. God needs something other. If it's not going to be just part of god, otherwise there will be no creation. I meanthe nature, that there is something other thangod. Am it may, in the end, come from and come back to write that god we that divine essence, or that whatever.
