Is it right?

It starts as a twitch,
One thought in the back of your mind,
A voice that whispers in your ear,
"Kill them" they say,
"Kill them" they desire.

At first you can resist it,
Only sticks and stones you think,
Soon the voice returns,
"Kill them" it says,
"Kill them" it desires.

Slowly you can't resist it,
Sticks and stones aren't the only things that hurt,
The voices whispers more,
"Kill them" it says,
"Kill them" you start to desire.

Sparks fly, knives sharpen,
The plot unfolds,
Their demise clearing day by day,
"Kill them" it says,
"Kill them" you repeat.

In dark of night you await,
The shadows hug you like a lover,
Seeing them quickens your heart beat,
"Kill them" the voice screams,
"Kill them" you desire.

You grab them now,
Pulling them into the shadows,
Taking out the knife,
"Kill them" the voices cry,
"Kill them" your soul desires.

You see their face,
A river of tears and pleads of life,
Your soul tightens,
"Kill them" it continues to desire,
"Kill them?" You question.

Your body shakes,
Regret filling your soul,
Sticks and stones you think,
"Kill them" it urges you,
"I'm satisfied" you think.
