Well we can assume that if God does exist and gave people a habitat where good and evil could equally influence people, then God gave people free will. And because God gave people free will, meaning in this context that people have the ability to make decisions independent of what God wants, people can freely choose to act good or evil. So the origin of evil doesn't come from God creating evil but from God creating people which brought the existence of evil upon themselves. Because God was not the one who created evil, mankind is responsible for the creation of evil and because of this evil events could never disappear from human life. The only way that evil events could disappear would be to have mankind
