I fear the tongue

I fear the tongue,
That boneless twisted
Flexible tongue,
Everchanging,
Though it's kept strung,
The weapon
That can save,
Create, annihilate,
Keep you enslaved,
That makes kings,
Turns them in to nothing
In a day,
That which can start wars,
Can create demons out of
The most sessile,
Which can blind you,
Keep you curtailed,
Yet like all great weapons,
It's power lies,
With the one who wields,
For I fear the wielder,
Fear the intention,
For it could be just your
destruction.
