If it has a pulse,Take its skull!If it builds a house,Smash it flat!Strength is my God,The God of Shapes,If my God should fail me,I will kill him too.— Sword Law Mantra of the Knights Belligerent, Kill Six Billion Demons
Tell them ruin has come to their world, death, despair and red war...
Tell them their hopes and pride have come to nothing.
Tell them their empty whispers fall upon deaf ears - their gods are dead, human logic has killed them.
Tell them the Angels of Death have come.
Tell them that nothing can save them now.
— Perturabo, Primarch of the Iron Warriors, Warhammer 40,000

Raiders are nasty, but they can be bargained with. They want your weapons, your supplies, your vehicle, and you can trade your life for these things. They also want to live, and you can trade your safety for their lives, should you be well-armed enough.
Warlords, likewise, are nasty, but can also be survived. They want control and obedience, and they care about stuff of the old world, like symbols and status. Grovel at their feet, or prove your usefulness, and the warlord might let you live.
The Ash Legion is not like any of these. These people genuinely, actually want to kill you.
