You can tell an enemy force is downright evil when its members don't even support each other. Sure they have a common goal, but it's every mook for himself. One mook will get injured and go down, the other will mock him and/or kill him. But why stop there? Use his body as a shield! Steal his stuff! Desecrate his body! Do We Have This One?? Needs a Better Description, at least one more catchy. I feel that this trope is applicable to many different works, so please add if you can! Thanks!
