Agree with what you say, disagree what I said is wrong. If Adelene is anywhere near a typical human, then the defection modules in her brain will never find a way to screw her friends over that would be worth the cost. They won't search for very creative ways, either, because that could be dectected by an enforcer - she has modules in her brain that do that, because specimens who can't convincingly fake such modules are eliminated. This fails in some cases, but the base rate of sociopaths, or bargains offered by entities who can guarantee secrecy, or chaos that makes enforcing harder, is low.
