Anger is a tool

People view anger as a bad thing.
I know because I was one of them.
Then I began to think. Anger isn't a crime. It's a tool.
Anger fuels rage, which in situations that impact my life, can be a benefit.
As I type, I let the darkness in my soul well up, compounding upon my rage, building it.
My anger swirls like a tempest.
The wings of truth and justice that lie upon my back warp and twist into demon's wings, filled with fire and hate.
Hate for those who hurt me.
Hate for those who spurn me.
Hate to those who don't know.
Hate to myself for not letting go.
The beast is unleashed, but under the guise of a friend.
Now to manipulate to my own selfish end.
