No, unfortunately that is not it. Trust me, I like the Cabal, Cayde was right, bug on honor but their actions say otherwise. The reason the Cabal smashed a ship into the deadnaught was for entirely different reasons then you think. Cabal reports show that during various encounters with other races, the "Gaurdians" are the ones that prove the most troubling, especially after "re-integration" they observe, pretty much being revived by their ghost is what the cabal are seeing, they find out that we gaurdians are somethimg called, "dead people". Phobos, meanwhile, recieve a report of an unusual occurance by the reef an deploy the Fleet to investigate, leaving the base bare bones security. Phobos is hit. Reports eventually show that the Hive are making pre-emptive attacks and guardians interference is causing more problems. Guardians are observed, "looting bodys", dismantling an repairing equipment on site, "Dancing" and performing "aerobatics" on light vehicles, from one Cabal report. During the events of the Taken King, it was surmised that the Hive were the only race with capable offensive strategies utilized to counter Guardian resurrection. Thus a message fron emperor himself, utilize whatever remaining force you have, attack the Hive Flagship, establish a beachead and compile any and all data you pertaining to Guardians and Hive tactics. --- With all that being said, that was the inital reason for the beachead, the events afterwards is what transpires during the story mode because the Cabal were not familiar with just how trully power Oryx really was. Can you imagine whats going through those cabals heads? Crash lands into a massive hostile dreadnaught, enemjes armed with weapons of arcane an meta physics, a being who can "Take" them and return them as slaves... Those scared Cabal, even inside their own ship, they are constantly fighting to stay alive, Hive in every dark corner, trying to operate under those conditons with a failing command structure and recons teams almost immediatly being butchered upon arrival. How long can the remaining cabal survivors last on the dreadnaught? Maybe a little longer under Vanguard hands?
