Raw emotion sometimes need to projected without structure, that's why we have free verse.
Macbeth: Act 1, Scene 5
"The raven himself is hoarse
That croaks the fatal entrance of Duncan
Under my battlements. Come, you spirits
That tend on mortal thoughts, unsex me here,
And fill me from the crown to the toe top-full
Of direst cruelty! make thick my blood;
Stop up the access and passage to remorse,
That no compunctious visitings of nature
Shake my fell purpose, nor keep peace between
The effect and it! Come to my woman's breasts,
And take my milk for gall, you murd'ring ministers,
Wherever in your sightless substances
You wait on nature's mischief! Come, thick night,
And pall thee in the dunnest smoke of hell,
That my keen knife see not the wound it makes,
Nor heaven peep through the blanket of the dark,
To cry "Hold, hold!""
Tell Shakespeare that he couldn't project raw emotion in a formal setting!
All poetry can project all emotion. Some people have this idea that free verse is anarchic in every sense. I don't think this is the case at all. I write mostly free verse, but to write well in free verse I find harder than say writing a sonnet. FV is not simply about starting to vent the first thing that comes into your head and calling it a poem. That way simply leads to prosey rants or self indulgent diary entry "poems". Anyway that's just my opinion as always.
