Dont tip my scales (libra)

I`m warning you: dont tip My scales
its taken years of fine detail
lifes see-saw with its ups & downs
the equilibrium so rarely found

For you behold a happy man
so bend and ear and I`ll expand
look to the heavens, its secret keep
our birthright, we are tied replete

 Storm or tempest headed not
all those hotheads loose the plot!
while others carp. wail and moan
just placid notes do I condone

To sail on life with even keel
still forge ahead with caution steeled
for the stars have cast my DNA
I cannot dispute or betray

 Balance at the fulcrums point
good and evils counterpoint
but honest John I tell you mate
I am the devils reprobate!

For I will tie the hangmans knot
or hold the bucket as a head goes plop
keen axe upon the neck did fall
 crowds all cheared at the bloody gaul

A black cap square upon my head
 crows will squawk for the feast ahead
for that is the sound that I revere
smell of death, balanced far or near?
