Fiction:Kwaad Interstellar Warrior Imperium/Culture

General Overview
The Kwaad are an aggressive species, reveling in war and the arts of torture. For them, giving and taking pain is a way of life. They live for the pain the cause, or for the pain they feel. How such a culture comes about is unknown, but the few times that they have spoken about it they have said

"The pain is all that touches us. Love, hate, fear, anger, these things do not touch us. They do not exist for us. Only pain exists to us, nothing else."

- Kwaad

which leads us to believe that, as a defense mechanism against predation the Kwaad lost their ability to feel emotions. They are now only capable of feeling pain, physical, not emotional. The Kwaad revel in this pain, for it touches them in a way that no other forces or things in this universe can touch them. It is the closest thing to emotion that they have left, and they want to teach that pain to all other creatures. naturally, being able to feel nothing but pain hasn't done much to improve their opinions of those who can feel emotions. They hate such peoples, who have what they can never have, and they try to destroy emotion wherever they see it.

Religion
The religion of the Kwaad is called "Dait Blicht", meaning "Pain of the Fallen" or more literally, "Fallen Pain". The main practices of this religion are child sacrifice (usually of the children from a different species), general sacrifice, giving of pain (torture), and the taking of pain (self-inflicted wounding). They have a decent number of ways they do this.
