Saphra, half the things you mentioned in your Cerberus list of 'successes' can hardly be called a success by the definition of the word.
-Project Overlord is almost fully wiped out, even if you keep David.
-Replicating the Normandy when you already have all the schematics? Not a matter of skill, just a matter of resources and time.
-Subject Zero project ended with the slaughter of pretty much the entire project, and Cerberus didn't even get anything out of Jack, as she broke free.
-Derelict Reaper is destroyed, and the entire research team was turned into Husks. Since nothing is ever mentioned of any actual research being used, so it's safe to assume that research mission was a massive failure. Shep's mission to retrieve the IFF is a success, if that's what you are referring to. That is more on Shep than Cerberus though.
-Gillian Grayson experiments are hardly a success, as, again, Cerberus has no control over Gillian. Creating a superhuman isn't exactly a success when that superhuman may very well come back to destroy you.
-Shep's body was recovered by Liara, not Cerberus.
-Horizon and Collector ship raids were successes due to Shep being involved, not Cerberus. The only thing Cerberus did to enable this was bringing Shep back to life (admittedly, their greatest success to date).
-Again, elimination of Shadow Broker due to Shep and his team...only initially enabled by Cerberus via the Lazarus Project
- Eliminating Paul Grayson was a success...allowing him to be freed and go on a rampage was a massive failure. So, basically, killing him was only good for covering up their big **** up.
