Allegiant question

The collapse of the Chicago:
If the Bureau created the Edith Prior video in the first place, why did it not want it released? The collapse of Chicago was not because of a premature releasing of the Edith Prior video, it was because Jeannine started a war by killing Abnegation then mind controlled Dauntless. By giving Jeannine the mind control serum, the Bureau only brought about the collapse of the Faction system.
However, even assuming the logic that the Bureau didn’t want the video released, The Bureau could have used the memory serum on the Abnegation to prevent them from even considering releasing the video.
The only rational explanation is that Veronica Roth had not thought of the memory serum idea until Allegiant.
Tobias had the option of giving memory serum to his mother or father, part of the drama of the end. Yet one option the Bureau could have done was to selectively give memory serum to the leaders, Johanna, Marcus or Evelyn, and effectively end the war themselves.
Even if Chicago couldn’t be saved, why reset the memory of all 4 experiments, including 3 other cities where apparently nothing was going wrong? The only plausible reason for resetting the memory of the entire population of 4 different cities was to give a justification for Tris’ actions.
If Matthew just invented an airborne memory serum, how did they reset Chicago for an earlier rebellion generations ago as David stated? Did The Bureau run around with guns and shoot every person in the city with memory serum decades ago?

If Divergent were so valuable, why allow them to starve as homeless Factionless, which is where the majority of them ended up?

The logic of The Experiments: If there really were Genetically Damaged people, then the way to eliminate them would not be put everyone with the defect together and have them inbreed, because that would only worsen their genetic mutations (like inbreeding Russian royalty intensified hemophila).
Why would wiping out the memory of everyone in the Bureau and reeducating them in a few days about the “correct” history even work, and why wouldn’t the US Government just import a whole new set of workers to replace the memory damaged ones from the “accident?”
Plus Tris admits that most of the Bureau is innocent, with her initial plan to give truth serum to the council to reveal their bad behavior to the rest of The Bureau. If anyone should have their mind wiped, it would the council only. By wiping out the memory of everyone in the Bureau, including the many innocent GD janitors, lab techs, etc. she effectively killed them, causing a lot of collateral damage. To justify her actions, she has Tris, the heroine who has spent the entire series with PTSD over shooting Will, hypocritically say, “These people have no regard for human life…they’re lucky I’m not going to kill them.”
Then, when confronted again with her idea of wiping out the memories of an entire population, Tris argues, “When you have to choose between two bad options, you pick the one that saves the people you love and believe in most, you just do,” a morale relativism which runs counter to the entire Abnegation morale code of selflessness.
It is implied that Death serum is the one serum no one is immune to, so if GPs/Divergents are resistant to cognitive manipulations such as Truth Serum and Simulation Serum, why aren’t they resistant to Memory Serum (because if even a fraction of them were, the logic of resetting The Bureau falls apart)?

Part of Tris’ anger at the Bureau is because she felt that they were wasting resources on the experiment instead of feeding the poor. So, war and rebellion are justified to stop a government mismanagement of resources?

If Peter would have never rescued Tris from her execution….it wouldn’t have mattered, since she’s immune to Death Serum anyway. She survived the more advanced Bureau’s death serum, so she never was in any danger being injected with Erudite death serum.

How does David’s explanation of GDs causing destruction never seen before on American soil become perverted into Nita and Matthew’s comment that there was never any war before GDs were created? These are two vastly different truths, and part of Tris’ plan is to show Bureau members footage of a war before GDs after she “resets” them. There is an enormous difference between “destruction never seen before on American soil,” which is believable given the large loss of life from the Purity Wars, to “never having had war” before the Purity Wars. There is enough loss of continuity between the 3 books, but this shift occurs within the same story.

Why would The Bureau create Experiments to modify behavior and provide them with advanced technology, such as guns, camera monitoring devices, and cars, so that they are harder to control, can more easily tear themselves apart, and can leave the city? If Experiments start out with everyone having had their memory reset, wouldn’t it make more sense to make them ignorant of all technology (like in “The Village”?). The technology the experiments were exposed to (cars and genetics and computers) and they were ignorant of (planets and geography) didn’t make sense. If the experiment had no access to cars, leaving the city in the first place would have been dramatically harder. If the Dauntless had to rely on clubs or knives to maintain order, the mass execution of Abnegation would have been exponentially more difficult. If the Erudite didn’t have death serum, there would have been no way for Evelyn to have a weapon of mass destruction. For some reason, no one in the Experiments considered the fact that they could have been monitored, even though the Dauntless were aware of the cameras around the city. If GDs in the Experiment start out with a blank mind, why even make them knowledgable about what a camera is in the first place? As for their cars, guns, camera surveillance system and computer network, how did the Experiments maintain them, keep ammunition, fuel, and parts working over 200 years without outside assistance? There was no “maintenance faction.” Speaking of factions, what did Candor do all day? They weren’t the journalists (that was Erudite), and their only implied function was lawyers, which seemed unnecessary as the factions handled affairs internally (Dauntless executed Eric, Abnegation arranged for Evelyn to fake her death).
