Monty really takes the whole cake.
He is the source of the Dark Side.

Pacifica's parents are the overall hate sinks.
I would choose Keith Szarabajka.
Ananzi
Mind Flayer is still scary. Vecna is its right-hand servant.
Ego is a bad dad.
Mysterio is a crime-framer.
I actually hate Arishem.
Because he is more powerful and vile than Thanos, which i love.
Thanos wanted to prevent Celestials' emergences from killing all life in planets, so he erased half of the universe for a good reason.
Damn the Celestials!
Bertram
ZA WARUDO! TOKI WO TOMARE!!!
HE IS MORE DEPRAVED THAN TRUMP HIMSELF.
CORONAVIRUS IS A COMPLETE MONSTER!!!
You should ask Sirin of The Void
To me, it's Chernabog.
