God created a perfect world, a world without evil. The evil we see today is as a result of the seed of corruption which was sown in the heart of men. God is not happy with the evil that is going on in the world today. He's intention for mankind is to for us to live a life of peace and tranquility.
There's a path that God set for us right from the beginning of time to follow but due to our rebellious behavior we worked contrary to that path which is set for us. When we go against the will of God they outcome is usually not good. We are to work in the ordinances of God. There's always rewarded that comes when we obey the word of God.
The Bible told us that the heart of Man is evil continually. The evil that goes on in the heart of Man keeps on becoming unimaginable as Time goes. The devil is always going around like a roaring lion seeking for who to before. He's looking for a means to get into the heart of men so that through them he can carry out his evil devices.
Those who are not rooted in Christ fall victims to this schemes of the enemy. But when we let Christ to take over us and the Holy Spirit to live through us we become free from the holds of the enemy
So many evil happening in the world today are caused by the disobedience of man.
