How does God tolerating evil not make Him evil?

**To clarify**, I'm not asking why God allows evil. I believe there are sufficient arguments for that. What I would like to know is: how can a righteous God **tolerate** evil without it affecting His nature as righteous? Are there any arguments for that, and is there any supporting evidence from the Bible to provide a basis for that belief? This question is based on a few passages: > Genesis 15:16 (NASB) : 16 Then in the fourth generation they will > return here, for the iniquity of the Amorite is not yet complete." This verse makes it clear that God tolerates evil, at least to some degree. > Psalm 5:4-5 (NASB) : 4 For You are not a God who takes pleasure in > wickedness; No evil can dwell with You. 5 The boastful will not stand > before Your eyes; You hate all who do injustice. This verse indicates that no evil can dwell with God. Righteousness cannot dwell with unrighteousness. However, what is the significance of God tolerating sin outside his dwelling as opposed to inside it? Not to mention that the omnipresence of God is taught in several places in scripture. Ex. > Psalm 139:7-10 (NASB) > > 7 Where can I go from Your Spirit? Or where can I flee from Your > presence? 8 If I ascend to heaven, You are there; If I make my bed > in Sheol, behold, You are there. 9 If I take up the wings of the > dawn, If I dwell in the remotest part of the sea, 10 Even there Your > hand will lead me, And Your right hand will take hold of me. I bring in this verse not to ask a second question but to show that even though evil is not in God's dwelling, it is still within the scope of His presence. This is to emphasize the question: how can a righteous God tolerate sin (for any duration of time) without being evil? Let me make the distinction more clear. **Why God Allows Evil:** This question concerns theodicy, which seeks to identify any conflict between a benevolent, omnipotent God and the evil and suffering in the world; in other words, it asks why a God who is good and powerful will allow evil to exist. **Why God Tolerates Evil on Earth:** This question focuses primarily on the evil that continues on earth, which means that God will allow or have some tolerance. Connecting to the broader question of why God permits evil, this question narrows the focus to understanding why God continues to tolerate its presence within our world.
