The heart of man is desperately wicked. The Bible says so. He always imagines evil. Doing what is evil is a delight to man. This is why there's so much evil in the world. God is not responsible for the evil things that are happening in the world. It is men who do all the evil that we are seeing in this world.
A God who created all things and concluded that they were all very good would not be the same one who is responsible for the evil. The Bible says that the whole world lies in wickedness. The world lies in wickedness because there are elements in the world who are evil doers.
We can make a difference. We will make the difference when we repent and turn away from every sinful and evil way. We can not to be evil doers. We can choose to allow ourselves to be used for doing evil. We can obey God always and do what is good.
