Promise a trial

"Your demand is to let you to commit a murder. I suspect it will include tortures. I can't allow it happen this way. Contrary to what you think we are not lawless band of thugs. He will stand a trial as a member of the tribe and I will judge him as I see fit. " the slaver is surprisingly calm if he doesn't care about his own fate.

"It didn't took long to execute those two who raped the girl. They shouldn't have tasted female flesh before their chief does, right?" You can bet that this former slave was a thorn in the ass for his owners. Someone like him can't be beaten into obedience

"Wrong. They ignored a direct order of the chief and my captains have a right to judge in such circumstances. I deeply regret that this happened and promise that from now on your women will be treated with respect"

"I don't mind if you or your goblins will use this bastard's daughter in any possible way. I enjoyed watching how two green dicks invaded his precious virgin girl. I hope now he knows how it feels when woman you love got raped" It explains why the slaver looks so broken "On other hand if you'll guarantee that my sister won't be touched, I will work for you and try to persuade others to do the same even if you decide to spare the life of that useless bag of fat"
