"Paths of Hate" by Damian Nenow (2010)

PLOT: "A short tale about the demons that slumber deep in the human soul and have the power to push people into the abyss of blind hate, fury and rage." (Description and below images via IMDb)

The illustration style first reminded me of the work of John Cassaday ("Planetary", "Astonishing X-Men", "Captain America" and "Star Wars"), actually. All good either way :)

Directed by Damian Nenow of Platige Image, this slice of Russian animation was released circa 2010.
