God Will Judge All.
None shall escape from either side for He is “not” a murderer:

“You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies.” – Lord Jesus Christ (John 8:44)

P/S:

You may be ‘right’ to kill your enemy (for your own reasons) but the ‘Perfect’ thing to do is ‘forgive’ and ‘lay down your life instead’.

There is “not” one command of Christ which allows a Christian to kill another for ‘whatever reasons’ under the Perfect New Testament established by Him for this ‘age’.

On the contrary, He exhorts us to “lay down our lives” instead (in all sense) should the need arise.

“We know love by this, that He laid down His life for us; and we ought to lay down our lives for the brethren.” (1 John 3:16)

‘Let them have the world for themselves if they do not wish to share it’ (The Way of Agape).

Remember, ‘The Highest form of Love, Agape doesn’t kill; it lets itself to be killed instead should such a situation arise’.

The very Manifestation of ‘Agape’ (Love of God) is Lord Jesus Christ Who ‘walked the Talk’ by laying down His Beautiful Life for the Redemption of the whole world:

“The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world!” (John 1:29)

Blessed Saviour of the World.
