Good poem but I feel you should add few more lines to it to elaborate the poem more.

I really liked this short piece, I do feel like you could elaborate it more, but for the short amount you wrote about you did a good job. You captured the terror and horror very nicely, and had me wanting more. My only suggestion is to add punctuation and change to this, it will read and look a lot better:

"Horror.
woman clothed in flames,
the furious mob burnt her alive,
the humanity shattered,
terror unvieled."

And "unvieled" should be "unveiled".

You have the talent that you could go way more into depth on this topic and provide much more imagery, that's just what I felt though.

4/5 from me, have a good week.
