Noah immediately got drunk after the Flood and cursed one of his sons for acting improperly.
Abraham pimped out his wife so he could survive, didn't sacrifice to God when his non-bastard son was finally born, and let Sarah browbeat him into sending his concubine and firstborn son to die in the desert. Also was willing to kill Isaac and lied to him about it as they walked to the sacrificial altar.
Isaac let his sons try to screw each other over, ultimately acquiescing to his younger son fucking over his firstborn. Let his wife take sides with their children in the process, screwing over Esau, who literally did nothing wrong.
Jacob's entire life was basically fucking with people—he literally fought with God and was given the name Israel for it. He let his daughter, Dinah, get carried away and raped, then let his sons slaughter the entire tribe even though they had willingly circumcised themselves because Dinah's abductor fell in love with her and wanted to do right by her family. It says a lot that when Jacob finally meets up again with Esau after fucking him over, he thinks Esau will certainly kill him because of how bad a person Jacob was, so he sends all his kids and wives and belongings ahead of him to meet up with Esau first. When Esau meets a super frightened Jacob, scared because he knows how much he has fucked his only brother out of everything that should be secured to him as the firstborn, Esau just says it's all in the past and that he wouldn't hurt the brother he loves.
Joseph was a bitch to all his brothers and then when they came to him in Egypt begging for food, he hid his identity and fucked around with them until they couldn't take it anymore.
Moses directed the Levites to massacre 3000 Israelites in the Exodus. Also disobeyed God at various points, as with striking the rock to produce water. Made an idol of a serpent to cure the Israelites of poison (Numbers 21, look it up).
Joshua didn't massacre all the people living in Canaan like God told him. He even got tricked by some clever foreigners into adopting them as part of Israel, against the commands of God.
Almost every judge was shit. Gideon made idols. Samson was a retard and a fucking simp for a Canaanite whore. Jephthah chopped up his daughter into twelve pieces. Deborah is unique in not doing anything bad, so you can add her to the list of good Israelites with Samuel.
Saul disobeyed God's commands on what to do with spoils of war, went crazy from a demon, and tried to kill David like 9 times. One of his sons was named Mephibosheth, meaning "from the mouth of shame". Why such a weird name? Because every time you see a name ending with "bosheth", it's replacing the word "Baal". Yeah, Saul named one of his kids after Baal (and he wasn't the first or last Israelite to do so). Saul broke the division of life and death by using necromancy to call Samuel's soul back from Sheol, which Samuel's ghost yells at him for. Saul commits suicide (though it's soft-rebooted in the beginning of 2 Samuel).
David killed people and stole their wives. He let his kids rape and kill each other. He promised to keep his best friend, Jonathan, safe, and then the Philistines desecrated his body. He sleeps around with Saul's daughter, then turns her against him by debasing himself before the Ark of the Covenant. When she complains, he tells her "well, the other women like it!" and God curses her. He takes a census against the commands of God, leading God to send a plague upon Israel. Also he had idols.
Solomon married a ton of foreign bitches and then built idols and pagan sanctuaries for them. He explicitly turns into a Pharaoh-like figure by gathering up large amounts of horsemen. He was a lustful man whose death caused an irreversible split of the Kingdom of Israel into two separate kingdoms.
You can go on and on and on. You'd think us Jews would learn from our mistakes by now.
