The evil of human nature and God

peace.
The Bible implies that God created us flawed – “The inclination of man’s heart is evil from his youth” (Genesis 8), “For there is no man who does not sin” (1 Kings 8:12-16), “No living person will be righteous before you” (Psalm 153), “For there is no righteous man on earth who does not do good and does not sin” (Ecclesiastes 7). Freud summarizes this in his work ‘Culture Without Discontent’: “Man is not a gentle creature in need of love, capable at most of defending himself when attacked. Among the impulses he is endowed with, he may also include a considerable degree of tendency to aggression. Therefore, for him, the other is not only a potential helper and a sexual object, but also a temptation to satisfy his aggression, to exploit his labor power without reward, to use him sexually without his consent, to take control of his property, to humiliate him, to cause him pain, to torture him and to kill him. Man is a wolf to man. In the face of all the trials of life and history, who would find the courage in his soul to deny this assertion?”

A. Why did God create his nature this way, so that he could have an excuse to harass him, abuse him, and destroy him time and time again – as we see throughout the Bible? To whom does he have to blame the works of his hands?
B. Why destroy and not repair?
C. Didn’t He really think through everything when He created the world?
D. You claim that it is not God who does evil – but man. If man is God’s creation and God created him this way, what are you actually claiming here?
God. Throughout the entire Bible we see God’s cruelty and capriciousness. Isn’t this proof enough for a believer? (What was enough for me, even a ‘small’ thing like the death of the fire that came at his command to sever all ties with him?).
