Although they may have a bad rep for the small massacres they are known for, they in my mind are one of the most heroic chapters. Seth knows the chapter will one day be extinct, and that day is soon, but he isn't going down quietly. The Flesh Tearers are now the one of the first to respond to any distress signal they find, and they have racked up victory after victory. They are still Sons of Sainguinias, they are still loyal and have honour, they just show it differently. They know their dyeing day is soon at hand, and they are going to the Emporers side dragging the enemy down with them.
