I'd prefer something inbetween.
If the alien is being weaponised... I dont see how you can marry that logic to the Jockey being peaceful. Thats a pretty horrific weapon they designed there. Keyword is if of course.
I'd like to see a creature that is driven by a logic. like what some conspiracy theories suggest the Alien Grey's to be like, there brutality stems from a lack of ... Empathy. They have no emotional connection. They are driven by the machine, by logic. Whatever is deemed most effective, or the most logic route, is the route they will take. If that means experimenting on humans to evolve a deadlier breed of alien, or something, thats what they'll do.
On the other hand, if a Jockey see's no logic in not helping a human to escape, or see's the logic that the aliens are too great a threat to allowed a continued existance, that they might destroy them all. Or die trying.
