i think The reason theres evil in the world is not because of God, but because God gave us the freedom to choose. Now the potential for love outweighs the existence of evil, because you see, evil is only going to exist for a short time, but love is going to go on forever. And all of the suffering and all of the death that we see in the world today are the result because man has chosen to make wrong choices.
so what is you clarification on that question ?
evil occured when god created man , when adam and eve eats the sacred fruit in garden of eden. That is the story that told me when i was young and i think that is true. Because nowadays there are many evil beings in this world. They kill innocents people , rape women , and doing more evil deeds to others. And because satan is the source of all evil.
