Last straw

There's the tale of this guy,

A moron, of unseen levels

Egotistic, ignorant and despised

He bickers and in it revels. 

Constantly insults are strewn,

The coup de grace, however

Was the unnecessary use of brawn

A narcissistic abuse of power.

An offer to help is snubbed

And, slurs and slights thrown,

Relationships are flubbed, 

Seeds of resentment sown.

Family and friends, for him

Was just to use and dispose

Mistreating others at whim,

Pummeling them into throes.

Admission of a weakness,

is akin to an Armageddon,

While confused with meekness,

his aim is of others deaden.

Like with the candle's flame,

we get burnt, due to proximity,

Mental disorders claim, 

Souls and commits to toxicity.
