Where did evil come from?
Again, it goes back to the creator, God who is perfect. He created a perfect world with perfect people. A part of the perfect people that God created is that they have the ability to choose between two viable options. It is apparent that God did not want mankind to be a robot that just automatically did what He wanted it to do but rather He wanted people who would love Him and prove their love for Him through the choices that they make. The first choice made available to mankind was to obey God and not eat of the forbidden fruit of the tree of the knowledge of good and evil. Out of all the trees in the garden, hundreds, perhaps thousands, there was just one that they could not eat, but Satan tempted them and they made the wrong choice. That is when sin entered into the world and with sin came death and decay (see Romans 5:12). With death and decay came natural catastrophes and all matter of illness and disease. All with just one act of disobedience. Sin is now the natural inclination of mankind. However, the results of sin can be reversed by an act of obedience. Therefore, by the act of our Lord Jesus (Romans 5:18) eternal life is now available for all who obey Him and believe on His name (Romans 10:13). We see then how sin was not created by God but because of the ability to choose, sin became possible and with sin, evil and death.
