It has nothing to do with having lust for blood. It is rather to stop those that do!
If you have a rabid dog, and most that make it to death row are possessed animals, you put them out of their misery and society’s.
The Prince of Peace also gave the command to kill the wicked as a surgical removal to avoid the spread. The wages of sin are death! Romans 3:23
When He returns to this earth the Second time it will be with the Wrath of the Lamb!
Revelation 6:12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
13 And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
14 And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.
15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
17 For the great day of his wrath is come; and who shall be able to stand?
2Thessalonians 1:6 Seeing it is a righteous thing with God to recompense tribulation to them that trouble you;
7 And to you who are troubled rest with us, when the Lord Jesus shall be revealed from heaven with his mighty angels,
8 In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ:
9 Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power;
10 When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day.
Do not mistake meekness for weakness! He is the Prince of Peace and the Righteous Judge that will destroy the wicked!
