The hive exist, or desire to please the survivors. However they want. Koumba has used this more than anyone else to his own advantage to live the life of a decadent, hedonistic and shallow playboy - roleplaying as James Bond and surrounding himself and having sex with women. Now, to me - this is very much - at the minimum - taking advantage of them. The women he’s having sexual relations with are not who they were, and it is unlikely - even if the hive came to him and suggested it (as I suspect they did) - that the women before the joining would be remotely interested in doing this. They are not them. Who they were has been lobotomised, malformed and disappeared into the hive - segmented up into billions of bodies.
