This poem is rather short but speaks well enough; It brings out the rage felt by folks and the wild actions committed by a person in anger, its just like the person you knew once has completely changes engulfed by "ANGER: One of the seven sins"

Anger

In Everything I said, 

I’d wish my foe was dead,

Scorching like the magma of several volcanoes, 

And through the veins it flows, In me;

Every drop of blood had to boil,

But right now I'm like dust,

I horrify folks 

I concur; dipped in anger until it soaks, In me;

Every time there’s fire in me, that’s never put out,

I don't inspire you, there's no doubt, 

For every tiny reason, 

Heart's filled with poison, In me.
