1) How? By shouting at them?
2) Most of the Cerberus actions we see are plainly trolling. TIM has nothing to gain by disturbing the war effort. His version of controlling the Reapers is far from perfect. He still needs time. Guinea pigs for the experiment are not the problem. The limited time is one. If he sabotages the galaxy alliances, he weakens the resistance against the Reapers, thus losing time.
3) His plan is going nowhere. On the contrary, he's just sawing off the branche he's sitting on.
4) It is, indeed. But that's not the problem.
5) Then the Reapers are going an incredibly hard and costly way to win the war. Or really having fun by making the war lasting more than it should, thus increasing their own losses. They're known to be highly efficient though. Taking the Citadel is the fastest way to destroy any organized resistance.
6) I don't buy the experiment thing. They're not interested in it. For them the story is already set in stone: Organics never change, always build robots and then die by the robots. They've calculated their cycle precisely so the organics don't suffer a total extinction because of robots they never face never ever face a too strong opposition. The only experiments I saw them trying is how to successfully merge Batarians with Humans or Turians with Krogan,so they can have cheap canon fodder.
7) No. The keepers being hacked wasn't planned. Sovereign losing thousands of years to open the Citadel and then miserably fail and die while the brat Catalyst was taking a nap wasn't planned. The whole freaking third game's plot wasn't planned.
1)No. Through the Citadel appearing (even though it isn't) to be the only refuge left in the galaxy from the Reapers. False hope, channeled not through the Council this time, but through Cerberus (and thus the Reapers).
2)He knows he's short on time regardless. He doesn't care how long the Alliance stalls the Reapers - only that they are stalled. He doesn't want an Alliance that can work enough with others to allow the construction of a Crucible that can Destroy the Reapers. That's what he's trying to keep from happening. He wants control over the Crucible (first its plan, then its construction, and eventually the machine itself), and we keep him away from that, just as he tries to keep us away from forging alliances and unifying with aliens.
Mars - Keep plans from Alliance, and thus the Crucible
Sur'Kesh - Keep alliance with Krogan from happening
Bomb - Keep alliance with Krogan from happening
Grissom - Gather subjects for indoctrination, especially with engineering expertise
Citadel - Take Citadel, use it to coerce others into working with Cerberus instead of allying with Alliance
Ex-Cerberus Scientists - Take out resources that have turned against Cerberus, before they can help the Alliance
Thessia - Gain confirmation of the Crucible's nature and workings, and thus the steps to take next
Sanctuary - Gain confirmation of the prospect of Control over things of Reaper nature, which combined with understanding of the Crucible, is enough evidence for TIM to made a more deluded attempt for the Crucible
Cronos Station - Put up a defense and stall Shepard and the fleet, while TIM aims to be ready for the Crucible's integration with the Citadel..
3. By 'going forward', I mean in his own mind. He's the bad guy, you know? He runs off from a logical basis (the Reapers are just old machines that can be controlled as machines) and personal bias (humanity first, through directed evolution), that in his own mind advances with every step. He's never proven wrong, just yelled at by Shepard.
4. Kay.
5. They don't consider it a war. At most, the one Reaper says "finish your war". To them, it is but an acceptable loss as long as their agenda is advanced. At first, this would be to let the Reapers in to commence the Harvest (ME1). Later, it is to incorporate humanity into a capital Reaper (ME2). Once other factors come into play, yes, they do sit back and take some hits on the chin for the 'greater good', as they define it.
They don't want to eliminate all resistance at this point. They want to channel the resistance into a solution. Again, even as Shepard resists in ME1, he impresses Sovereign. And then in ME2, we have Harbinger seemingly fixated on Shepard. And now in ME3 we can get a clue why.
6. Yes. They suck. They're not seriously looking for a solution. However, imo, after the events of ME1-ME2, they're looking for one more than they ever have. The monkeys are rebelling. They're keeping us from entering the lab. They're disrupting our tests. They're running through the hallways and breaking the restraints. Maybe if that was happening, one might be curious about it? Being curious doesn't mean that they're sympathetic or cooperative. It just means that they can allow the experiment to continue in another way. They'll wait for Shepard anyway. He can have his war, and ascend regardless.
7. Can I swap 'planned' for 'understood as a logical possibility'? They're giant machines with supposedly benevolent motives. If they wanted to, they could just hack into us Matrix style and not even bother with any Harvest. The Citadel+Cycle system was the best they could do with what they had, and the goals they wanted to achieve. I don't believe that Synthesis or whatever was planned from the start by the writers (of course it wasn't), but this works just as well with the Dark Energy prospect. In either case, the Reapers let organics exist for a time, knowing that it could backfire on them to some exist, but being confident that it won't. You'll find that attitude with scientists all the time, so add in robo-god and....
