Analysis of Poizenous angel

When all routes but one
Are clotted by the final ray of sin
One route back to heaven
Already begun
Held by a lifelong love
To a holy friend of light
The final soul on earth
In all terror and all might
Then scorched was the earth tree
And the final route dried up
By one final angel's
Release of hatreds foulest cup
For it was the final deaths
Of women dragged by man
Then lesson could be supped
When new was the godly plan
