When we think about sinners in the Bible, certain names pop into our heads, and some of these people are just straight-up villains. But have you ever considered who might be the most sinful of them all?
This article looks at 14 people in the Bible who committed some pretty serious wrongdoings. You might be surprised by who’s included—and who isn’t. Let’s look closely at their stories and see why they’ve earned a spot on this list.
Judas Iscariot

Judas Iscariot is perhaps the most infamous of all. He was one of Jesus’ disciples, but he betrayed Jesus for 30 pieces of silver. This betrayal led to Jesus’ arrest and crucifixion. What makes Judas’s actions so sinful is that he was close to Jesus and still chose to turn against him. His greed and possible disillusionment led him to commit one of the most famous betrayals in history, marking him as one of the most notorious sinners in the Bible.
Jezebel

Jezebel, the wife of King Ahab, is known as one of the most wicked women in the Bible. She strongly supported the worship of Baal, even killing the prophets of God who opposed her. Her manipulation and evil deeds didn’t stop there—she also orchestrated the murder of Naboth to take his vineyard for her husband. Her actions show the dangers of unchecked ambition and idol worship, making her a symbol of evil in the Bible.
King Ahab

King Ahab, Jezebel’s husband, was a king of Israel who led his people into deep sin. Under his rule, the worship of Baal flourished, and he ignored God’s commands. Ahab’s most sinful act was allowing his wife to commit murder to gain a vineyard, showing his complete disregard for justice and righteousness. His legacy is one of weak leadership and moral corruption.
Herodias

Herodias is infamous for her role in the beheading of John the Baptist. After John condemns her marriage to Herod Antipas (her former husband’s brother), she harbors a grudge against him. When her daughter Salome danced for Herod and pleased him, Herodias seized the opportunity and asked for John’s head on a platter. Her desire for revenge and her ruthless actions make her one of the more sinister figures in the Bible.
Delilah

Delilah’s name is synonymous with betrayal. She was the woman who seduced Samson, the strongest man in the Bible, only to betray him to the Philistines. She tricked Samson into revealing the secret of his strength—his uncut hair— and told the Philistines about it, leading to his capture, blinding, and eventual death. Delilah’s willingness to deceive for personal gain highlights the danger of misplaced trust and the destructive power of betrayal.
Ahaz

King Ahaz of Judah was known for his unfaithfulness to God and his involvement in idol worship. He brought the worship of foreign gods into Judah and even sacrificed his own son in a pagan ritual. Ahaz’s sins didn’t just affect him—they misled his entire nation. His reign was a dark time for Judah’s spiritual life, showing how much harm a leader can cause when they turn away from God.
Herod The Great

Herod the Great is best known for the Massacre of the Innocents, where he ordered the killing of all male infants in Bethlehem in an attempt to eliminate the newborn Jesus, whom he saw as a threat to his throne. Herod’s ruthless pursuit of power, even at the cost of innocent lives, makes him one of the most wicked rulers in the Bible. His paranoia and cruelty left a bloody stain on history.
Cain

Cain, the firstborn of Adam and Eve, is known for committing the first murder in history. He killed his brother Abel out of jealousy because God accepted Abel’s offering but not his own. Instead of trying to improve himself, Cain let his anger and envy take over. This tragic act showed how dangerous unchecked emotions can be and set a sad example of human sinfulness. Cain’s story serves as a reminder of the harm that jealousy and anger can cause if we don’t control them.
Abimelech

Abimelech, one of Gideon’s sons, is remembered for his brutal quest to become king. Unlike his father, who refused kingship, Abimelech was driven by ambition. To secure his position, he committed a horrific act—he murdered his seventy brothers, wiping out his family to eliminate any rivals. This ruthless act showed his total disregard for human life, even within his own family. Furthermore, Abimelech’s rule was marked by violence and treachery, as he continued to use force and deception to maintain his power. However, his reign was short-lived and ended in disaster. During a battle, a woman dropped a millstone from a tower, fatally injuring him. In his final moments, Abimelech ordered his armor-bearer to kill him with a sword, so he wouldn’t be remembered as having been killed by a woman (Judges 9:54).
Haman

Haman, the villain in the Book of Esther, tried to wipe out all the Jews in the Persian Empire just because one man, Mordecai, wouldn’t bow to him. Driven by pride and hatred, Haman planned a genocide against the Jews. But his scheme was discovered and stopped, and he ended up being executed on the very gallows he had built for Mordecai. Haman’s story shows how dangerous it can be when pride and hatred take over.
Saul (Before Becoming Paul)

Before his dramatic conversion, Saul was a fierce persecutor of Christians. He was responsible for the imprisonment and execution of many early believers, thinking he was doing the right thing. Saul’s harsh actions against the early Church makes him one of the Bible’s most notorious sinners. What makes Saul’s story so powerful is his transformation—he went from being a major sinner to one of Christianity’s greatest apostles, Paul. It’s a testament to how anyone can change, no matter their past.
Pharaoh of Exodus

The Pharaoh of Exodus, likely Ramses II, is remembered for his stubborn refusal to free the Israelites from slavery, despite witnessing God’s powerful plagues. His hard heart led to the suffering and death of many, including the loss of his own son during the final plague. Pharaoh’s refusal to obey God and his harsh treatment of the Israelites make him a deeply sinful figure in the Bible.
King Manasseh

King Manasseh of Judah was one of the most wicked kings in the Bible. He reintroduced idolatry, set up pagan altars in the temple, and even sacrificed his own son in a fire. His reign was marked by extreme evil and led to the spiritual decline of Judah. Although he repented later in life, the damage he caused was huge, making him one of the most sinful figures in the Bible.
Nebuchadnezzar

King Nebuchadnezzar was a powerful ruler who let his pride get the better of him. He built a massive golden statue and demanded everyone worship it, under the threat of death. His arrogance was so extreme that God humbled him by making him live like an animal for seven years.
