one who follows, usually without asking the why, for the side of evil
don't be a henchman!
stand on your laurels
do what no one else does
praise the good of other men for good man's sake
and when everyone else in the world follows your lead
(although a cold day in hell it will surely be)
that's when the entire world shall live in harmony
Verb. The sudden, unexplained (or barely explained) death of henchmen, soldiers or underlings that occurs once their leader has been killed.
Considered a tired trope used by lazy writers; primarily in science fiction and fantasy works.
"Season 8 of Game of Thrones should be erased from existence."
"Oh - agree completely. The worst part was when Arya kills The Night King, and they fucking Henchmen Domino'ed the White Walkers."
