monstrous responsibility

i may be a monster
but i possess some good
which i see is inconvenient
to the ending of your book

i may be a monster
but it’s implied that i was made
every wall was built
every evil brick was laid

which part did you construct?
what sins did you leave behind?
what dark design did you
conjure with your mind?

I’m simply a mirror
held to the face of man
when i’m wielding the ax
my hands execute your plan
