This question that you asked was one that I had too, before I began to study these doctrines, and sit under preaching that was directed out of this theology. I will try to help answer your question. First of all, consider the God that the scriptured teach. Our God is Holy, Just, Righteous, Omniscient, Omnipotent, Omnipresent, Full of Grace, full of Love and full of Wrath. Our God is no more full of infinite Love as He is full of infinite Wrath. God does not exist for man, He is fully for Himself and His own Glory. God's thoughts and His ways are far above our ways. We cannot, with our finite human minds try to comprehend a God who is fully infinite. With that in mind, I'll try to explain

Romans 11:33-35 says, "Oh the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out! For who has known the mind of the Lord? Or who has become His counselor? Or who has first given to Him and it shall be repaid to Him?" Now, your objection to this "Calvinistic" belief may be, How can God blame anyone for sin and unbelief when He has sovereignly determinde that person's destiny? But, the Bible answers your question with, Romans 9:18-24 "Therefore He has mercy on whom He wills, and whom He wills, He hardens. You will say to me then, 'Why does He still find fault? For who has resisted His will?' But indeed, O man, who are You to reply against God? Will the thing formed say to him who formed it, 'Why have you made me like this?' Does not the potter have power over the clay, from the same lump to make one vessel for honor and another for dishonor? What if God wanting to show His wrath and to make His power known, endured with much longsuffering the vessels of wrath prepared for destruction and that He might make known the riches of His glory on the vessels of mercy, which He has prepared beforehand for glory, even us whom He called, not of the Jews only, but also of the Gentiles." Evil's presence and contamination is for God to demonstrate His wrath, to make His power known, and to put the riches of His glorious mercy on display. No one is treated unfairly: Some receive the justice they earn and deserve, others graciously receive mercy. (These notes come from the Macarthur Study Bible)
Psalm 76:10 says, "Surely the wrath of man shall praise You; With the remainder of wrath You shall gird Yourself." But the Bible also says in Ezekiel 18:23 "Do I have any pleasure at all that the wicked should die? says the Lord God, "and not that he should turn from his ways and live?" in verse 32 of the same chapter, the Lord says "For I have no pleasure in the death of one who dies," says the Lord God.'Therefore turn and live!'" While God is sovereign in salvation, man is still responsible to repent and believe. Our God is not a bloodthirsty sadist. He takes delight and is praised when His holiness is vindicated. Sin must be paid for, and God's law must be vindicated. He takes glory in that.We cannot fully comprehend God and His ways and why He does things. But we must accept His word as truth, and as a believer, we love God for these attributes

Hope that helps!
