I have been thinking about incubi-like code of honor after reading a bit of Path of Renegade. Had an idea of my kabalite Dracon being the last survivor of an incubi shrine after some wars between kabals, and simply taking up the rifle once more and going mercenary, then slowly building a raider warband through successful contracts and rumours. The warband would embrace the incubi idea of being perfectly focused on the art of killing and taking up something very much akin the incubi code of honor. However, as one requires to take up the incubi suit through besting one in single combat, the warband would be forced to stay as they are, unable to progress further into a new shrine.
The reason for such thinking was because I use Kabalite warriors for holding objectives, so I figured they had to be a disciplined bunch that could hold the line, rather than shrieking madmen. What better way to have discipline than to practice the incubi ways of being as efficient as possible?
Your guys could be something similar. Perhaps the followers of an incubi master that fell from grace and was taken out in a very inglorious manner, maybe whose remains were later collected and taken to a haemonculus for revival, because the incubi master's apprentices desired to learn more of his secrets? Would at the same time give the reborn master a motivation in the form of revenge.
