Had a silly idea of what to do with excess prisoners from raids.
The idea is this: Since they have the hideous gene, everyone will hate them and consider them a rival. Then, I load them up with things that increase their speed, make them feel less pain, and anything that causes some effect on death (acid blood, explosion, etc.)
This way, they can have this implanted, be enslaved, and then forced to suicide charge into enemies. Maybe it'll thin their numbers a bit, but more importantly, since everyone hates them for being ugly, everyone will be happy when they inevitably die!
I should probably add some gene that prevents them from talking, so they don't end up building relations through conversations and become non-hated.
