Death threat (dive into the dark end)

Scribbled long
pain filled letter
death matters,
life in tatters,
unending wish list,
deeds to be done
extremely injurious,
poisonous gun
nothing a surprise,
nonfactual surmise,
thrill dissipated,
vanquished starter
standing naked in
iced cold water
words assist in
lost purpose found
motivation chained
maimed and bound
deep daring questions
unachievable quests
Armageddon primed
catastrophe lest
opportunities dark
demon shiny sparks
continuous torture
blood soaked marks
each letter describe
blackened fate
dripping venom
hated hate
deeper than abyss
evening murder
evil madly runs away
assassins shudder
thoughts so red
blood appears white
parchment in possession
killed on sight
