‎Do I take any pleasure in the death of the wicked? Rather, am I not pleased when they turn from their ways and live? -Ezekiel 18:23

And from each human being, too, I will demand an accounting for the life of another human being.
Whoever sheds human blood,
by humans shall their blood be shed;
for in the image of God
has God made mankind. -Genesis 9:5-6

Do not gloat when your enemy falls;
when they stumble, do not let your heart rejoice,
or the Lord will see and disapprove
and turn his wrath away from them. -Proverbs 24:17-18

As surely as I live, declares the Sovereign LORD, I take no pleasure in the death of the wicked, but rather that they turn from their ways and live. Turn! Turn from your evil ways! Why will you die, people of Israel? -Ezekiel 33:11

You have heard that it was said to the people long ago, ‘You shall not murder, and anyone who murders will be subject to judgment.’ But I tell you that anyone who is angry with a brother or sister will be subject to judgment. -Matthew 5:21-22

You have heard that it was said, ‘Eye for eye, and tooth for tooth.’ But I tell you, do not resist an evil person. -Matthew 5:38-39

You have heard that it was said, ‘Love your neighbor and hate your enemy.’ But I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous. If you love those who love you, what reward will you get? Are not even the tax collectors doing that? And if you greet only your own people, what are you doing more than others? Do not even pagans do that? Be perfect, therefore, as your heavenly Father is perfect. -Matthew 5:43-48

You shall not murder. -Exodus 20:13

The avenger of blood shall put the murderer to death; when the avenger comes upon the murderer, the avenger shall put the murderer to death. -Numbers 35:19

Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him. -1 John 3:15

But the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars—they will be consigned to the fiery lake of burning sulfur. This is the second death. -Revelation 21:8

We know that the law is good if one uses it properly. We also know that the law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious, for those who kill their fathers or mothers, for murderers, for the sexually immoral, for those practicing homosexuality, for slave traders and liars and perjurers—and for whatever else is contrary to the sound doctrine that conforms to the gospel concerning the glory of the blessed God, which he entrusted to me.
I thank Christ Jesus our Lord, who has given me strength, that he considered me trustworthy, appointing me to his service. Even though I was once a blasphemer and a persecutor and a violent man, I was shown mercy because I acted in ignorance and unbelief. The grace of our Lord was poured out on me abundantly, along with the faith and love that are in Christ Jesus.
Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners—of whom I am the worst. But for that very reason I was shown mercy so that in me, the worst of sinners, Christ Jesus might display his immense patience as an example for those who would believe in him and receive eternal life. Now to the King eternal, immortal, invisible, the only God, be honor and glory for ever and ever. Amen. -1 Timothy 1:8-17
