Vengeance or faith

You shall live in fear,
For I must carry this pain.
For I can't drop a tear,
You shall die in vain.

I won't let you go,
Let your offspring survive,
For the truth I know,
I shall sharpen my knife.

The blade that'll kill you,
Will be sharper than ever in advance,
Can you already say adieu?
You do not stand a chance.
