The King James translation is either inaccurate or the meaning of the word "evil" has changed.
(Isaiah 45:7 NIV) I form the light and create darkness, I bring prosperity and create disaster; I, the LORD, do all these things.
(Amos 3:6 NIV) When a trumpet sounds in a city, do not the people tremble? When disaster comes to a city, has not the LORD caused it?
God didn't have to create evil. Satan, Adam, and Eve all rebelled on their own. Doing what was in their hearts to do.
