Singing witch

I have seen a witch that sings

Calling out things 

Things that have no name

Wandering through the thick forest

With crooked foot, barefoot

A loose noose around her neck 

She was hanged by it

She flaunts it, her final gift 

On the moonlit night 

She smiles at every passerby in sight 

eerie smile 

One can see her agony in her smile

Her home, ruins of a butchery by the lake 

She sings of some justice, which she crave

What justice?
