The worst people murdered for personal gain
There are many people in the Bible who committed grave sins but later repented. The first one who comes to mind is King David. David had an affair with Bathsheba, and eventually worked to ensure that her husband was killed in battle so that he wouldn’t find out. But he also repented and was open to doing things God’s way. The history of the church is filled with stories of similar sinners who became saints.
But when it comes to the really bad people in the Bible — and there are many to choose from — I narrowed it down to two. The first is King Herod the Great, who was King of Judea at the time of Jesus’ birth. Herod is the one who ordered the execution of all the 2-year-old boys in and around Bethlehem, because he felt threatened by Jesus’ birth (Matthew 2:16). We don’t know how many children were murdered, but we do know it was done to satisfy the desire to maintain power.
The second person I chose has a connection to Herod — Herodias, the second wife of Herod’s son Herod Antipas. She is the one who had John the Baptist murdered because he dared to speak out against their marriage. Like Herod, she conspired to murder someone for personal gain.
Ultimately, all the people we read about in the Bible can serve as examples to us — either of how to do God’s will, or of how to reject his will in favor of our own.

The worst person is not a person at all
Most people assume that Judas is the worst person in the Bible, but actually the worst person in the Bible is not a person at all … it’s a thing, or a fleshly manifestation called "pride."
Pride is what brought Lucifer down low from his exalted angelic position in the heavens, and pride is what brings men down low until this day.
The worst person(s) in the Bible are listed in Proverbs 6:16-19:
"These six things doth the Lord hate: yea, seven are an abomination unto him: A proud look, a lying tongue, and hands that shed innocent blood, a heart that deviseth wicked imaginations, feet that be swift in running to mischief, a false witness that speaketh lies, and he that soweth discord among brethren."
The devil is the originator, or the spirit, behind all seven of these abominable things. He hates God, he also hates men, but he uses men to accomplish his evil work.
If you are a student of scripture, you can find men and women in the Bible who manifested the evil listed in Proverbs 6:16-19. Shucks, you don’t really have to open the Bible to see them; you may be guilty of doing them yourself.
Judas was horrible, but he was chosen to play the part he played. What about you? Judas felt sorry for what he did, but he hung himself. Godly sorrow leads us to repentance, and ultimately to forgiveness of sin. God loves people, but He hates sin and wickedness.
