Midrash su Ecclesiaste 7:29

And the Lord said: Behold, man has become one of us (Gen. 3:22). Scripture states elsewhere in allusion to this verse: Behold, this only have I found, that God made man upright (Eccles. 7:29); that is, the Holy One, blessed be He, who is called righteous and upright, created man in His own image so that he might be upright and righteous like Him. However, if you should ask: Why did He create the evil inclination, concerning which it is written: The inclination of man’s heart is evil from his youth (Gen. 8:21)?, you say thereby: Since man is evil, who can make him good? The Holy One, blessed be He, contends: You make him evil! Why is it that a child of five, six, seven, eight, or nine years of age does not sin, but only after he reaches the age of ten and upward does the evil inclination begin to develop in him?

"without wrong": He did not create men to be wicked, but to be righteous, as it is written (Koheleth 7:29) "G-d made man just, but they sought many devices."
