Why God Created EVIL & Satan

IF God created all things good, where does evil come from?
Genesis 1:31 - And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
Isaiah 45:7 - I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.
Satan was originally created good and then he fell. God created Satan so God did create evil technically.

James Chapter 1: 11 For the sun is no sooner risen with a burning heat, but it withereth the grass, and the flower thereof falleth, and the grace of the fashion of it perisheth: so also shall the rich man fade away in his ways.
12 Blessed [is] the man that endureth temptation: for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him.
13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:
14 But every man is tempted, when he is drawn away of his own lust, and enticed.
