Who Am I? Friend, or Foe?

Since time immortal, I have stood,
No one name will do me good,
Known by many to all, and all to many,
Names are but glib pleonasms, spoken blindly,
Depends on your view, if I'm dark or friendly.
Who's the fairest of them all?
I can't see, my vision clouds in deep, blood red, all,
Watching those around the world drop like flies,
Day in, and day out, since the beginning of time,
Cryptic, I speak in stark and subtle rhyme,
Extrapolating from between every line I read,
Making more sense of each and every deed,
Done without forethought,
Before time to form a thought,
Already done, by the time I realize,
I'm not human, I don't even know if I have a real form,
I'm more of a swarm of stinging insects, or a raging storm,
I'm more of an alien, a celestial being, light
But prone to the dark thoughts that take flight,
When done wrong, or just don't like someone,
I'm older than pages long worn,
I'm the feeling that you find
In the recesses of your mind
That you've done something wrong,
Or in your gut, that something's off, something's wrong,
I'm the voice that whispers to you in that note of a song,
Makes you think on your phone someones calling you
Or with their voice, someone's calling out for you.
I'm the harsh dust that refuses to settle,
I'm the shrill whistling of the tea kettle,
The static shock in the Winter, when touched,
The feeling of being watched,
The urge to turn around when you can't look back
The twinge in your side or back,
The particularly dreaded chore,
I'm the numbness you feel in your core,
The superfluous and shallow formalities that bore,
The friendly lies that keep conversation afloat,
The deep, murky waters that keep boats afloat
And the harsh, tall, thrashing, waves that sink them,
I'm the gleam of a prized, guarded, gem,
The shadow hidden in the light,
The blood ensuing from a fight.
Just as rose petals start to dry with unique texture,
My omnipotence is a permanent and unique fixture,
I am always there, in the recesses of your mind,
Only you can decide if I am "evil" or kind.
