In fact, it is said you can't do a partial wipe because the droid's mind is too interconnected for this to not create problems down the line.
When was this said? It's prety obvious that they never do a *complete* wipe, because then a droid would be useless. 3PO's skills and personality change remarkably little after his memory wipe, showing that droids have a very sharp delineation between pre-programmed stuff and new experiences.
Hell, 3PO's personality was pretty much there upon his
activation. Almost 50 years of EU after that with one intervening memory wipe, his personality is much the same. It's pre-programmed. We can't know if the same would be true for R2 or for a B1, but that's the way it is with one of the most complex and human-like droids that we are introduced to.
So? There are stupid humans too, but no one questions their sentience.
Yes, but no humans exist that were engineered from the ground up to be good only at a) shooting and b) following Seperatist orders. Even the Star Wars clone troopers have human brains and despite some "programming" are meant to be effective, sentient, human soldiers.
Battle droids have not been shown capable of any serious thought, just as Lama Su said back on Kamino.
With B1s, there is hardly a debate. They are capable only, so far as we know, of assessing their own status (My legs aren't moving, I must need maintenance), yelling battle cries (Die Jedi dogs!), verbal acknowledgement (Roger, Roger), and warning (Uh, oh). They are also smart enough to take cover...sometimes. In their original use, on Naboo, they were all under the direct control of a central computer...they were given extremely limited autonomy after that.
OOMs are a different and more perplexing story. They are more independent, and they are capable of sarcasm (You're welcome) and able to give and recieve complex commands. Some even cry out as they are destroyed. It is, however, unlikely that the Trade Federation or the Techno Union programmed them to be capable of betraying them, no matter how many memory wipes were given or withheld. It is morally troubling to think of them all destroyed or shut down, but what else can be done with them? They aren't as bad off as the B1s, but they are still savants, with a brain only physically capable of doing a few things. It would be a massive project, if perhaps technically feasible, to perform a vast memory-dump program of all the quirky personalities of all the surviving OOMs from their extremely limited minds into droid brains with no restrictions on them and even then, it's debatable whether or not it would be the same droid. Moreover, it's difficult to imagine the Republic doing this, let alone the Empire.
B2s...not a lot of data on them. They do converse amongst themselves, similarly to the battle droids. They do express frustration with R2, but even the B1s can yell insults and the like. What limited data we have suggests that they are more comparable to the OOMs than the B1s. (You can even play one in the SW RPG.) Still, the only thing we see them do that's not shooting or capturing individuals is investigating the fighters in the hangar bay...but they don't seem to do anything other than note the existence of the fighters and then examine them, no doubt for later downloading to the ship's computer.
Droidekas...pish. They don't even talk. I'm no more disturbed by their destruction as I am of the other armored vehicles and ships.
Vulture fighters seem to express feelings of curiosity, and can "verbally" spit data back and forth. That doesn't prove very much, though. They are so specialized and hard-wired loyal that it's hard to imagine doing anything with them other than having the Xi Char give surviving units a total overhaul. At which point, it's possible to argue, of course, that it's not the same droid. Once smart war droids EXIST, moral issues are hard to avoid. Naturally, it was wrong of the Seperatists to build an army and mobilize in the first place, to BDZ Humbarine, etc.
Tri-fighters are brilliant "pilots" but don't seem to know how to do anything else They remind me of the Dark Empire TIE/Ds. Again, nothing to do with them but pick them up, deactivated, on a massive scale and reprogram them into Imperial craft.
Ain't that odd. A B2 knows enough to disable a Jedi Fighter, and definately considers itself to have superior intelligence to an astromech. Similarly, they can afford freaking vulture droids and tri-fighters in great numbers, but you think they can't afford 'smart droids?'
See my discussion above. I didn't see any "disabling" going on. Besides which, a bull elephant could "disable" that fighter just fine.
It puzzles me that you equate infantry units to high-performance fighter craft. Which of those two categories do you think the Seperatists needed MORE of?
Anyway, we know for a fact that they had "quintillions" of infantry droids. Even if we give the Seperatists an insane number of capital ships (a billion) and give them a ridiculously high average number of fighters each (a thousand) we have...a trillion high-performance fighters. Compared with quintillions of infantry units. Why on earth are you comparing these? To get an obscenely high number of infantry droids, make 'em dumb and cheap. To get high performance fighters that can take on human pilots, make them smart, which costs more, but that's okay, since you don't need nearly as many.
That's because Grievous summerily excecutes anyone who defies him, including the organic crew (RotS novel). You'd do it too if General Grievous told you to. If you have an iota of common sense anyway.
While I loved Grievous smashing heads in the book, let's consider here. By the time the Jedi are wreaking havoc on the bridge, the Neimoidians are OUT OF THERE. The ship's crashing, the Jedi are waving swords around, and Grievous is a little BUSY at the moment! There is also a total lack of blood spatters or bodies indicating that any Neimoidians were killed in their flight.
If you're a Neimoidian on the bridge and Grievous is yelling at you to "stay at your post," when all this is going on, you'd be thinking, "I have better odds running to an escape pod! The Jedi are going to be all over Grievous and we're plunging into the atmosphere anyway!" You wait until the General's back is turned and skedaddle.
If you're an OOM on the bridge and Grievous yells that, you think, "I'm staying here." You have no capability to defy him. Lapsing into Asimov-speak, your Third Law was overridden by your Second Law. And shortly, you die. Only the OOMs that weren't ordered by Grievous to stay ran.
To answer your point directly, common sense directs one to get the hell out of there. Grievous is in no position to back up his threats, and getting killed by him isn't much worse than burning up in the atmosphere anyway. Your only chance of survival is to escape. The OOMs don't have common sense. They have hard-wired loyalty and, subordinately, self-preservation.
