Why is there so much evil in this world? (Part 3 of 4)

Sin is the major reason why there is evil in the world today.
Romans 3:23 (KJV) For all have sinned, and come short of the glory of God;

Where there is no GOD'S glory,chaos,issues evil events become the order of the day.

Before sin came into the world through eve,there was no evil happenings in the world.

To me the major reason for these evil events is sin.
