Is God a moral monster?

Scriptures
Philippians 4:8-9
‘Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things. What you have learned and received and heard and seen in me—practice these things, and the God of peace will be with you. ‘
Genesis 16:3
‘So Abram’s wife Sarai took Hagar, her Egyptian slave, and gave her to her husband Abram as a wife for him. This happened after Abram had lived in the land of Canaan ten years.
Deuteronomy 21:18-21
‘“If a man has a stubborn and rebellious son who does not obey his father or mother and doesn’t listen to them even after they discipline him, his father and mother are to take hold of him and bring him to the elders of his city, to the gate of his hometown. They will say to the elders of his city, ‘This son of ours is stubborn and rebellious; he doesn’t obey us. He’s a glutton and a drunkard.’ Then all the men of his city will stone him to death. You must purge the evil from you, and all Israel will hear and be afraid. ‘

Dorothy Sayers
“For whatever reason God chose to make man as he is— limited and suffering and subject to sorrows and death—He had the honesty and the courage to take His own medicine. Whatever game He is playing with His creation, He has kept His own rules and played fair. He can exact nothing from man that He has not exacted from Himself. He has Himself gone through the whole of human experience, from the trivial irritations of family life and the cramping restrictions of hard work and lack of money to the worst horrors of pain and humiliation, defeat, despair and death. When He was a man, He played the man. He was born in poverty and died in disgrace and thought it well worthwhile.”
