Look who really cares about B4?
When it comes down to it, I'd rather have Data than B4.
And I'd rather have Spock than his cloney-thing created in the Genesis wave.
Yes stealing both bodies is ethically wrong but I don't think that I could stand more TNG Prime Universe with an even stupider Data.
The fact that it's "ethically wrong" is very much the point.
...not sure I understand the "ethically wrong" thinking, but I really want to...can either of you please expound?...
I'll certainly try.
Hm, I will first admit that "ethically wrong" is perhaps the wrong words, in terms of Data himself. Data holds no responsibility for his (allegedly) having overtaken B4's matrix, as it is (presumably) simply a 'happy accident' that he re-emerged in B4's body as presented in nearly all of the post-
Nemesis Star Trek literature (as well as Star Trek Online).
My point is that the writers of the literature essentially made a call that was "ethically wrong" when
they decided that the only possible outcome was for Data to come back to life.
As
T'Girl says, Data had no forward knowledge of his death (unlike Spock) when he implanted his engrams into B4's neural net. The idea he had was apparently simply to 'kick start' B4's development, but that he and B4 would then co-exist (with B4 hopefully learning and developing his own personality unique to Data's). That Data
co-incidentally died later in the same movie in my eyes doesn't change that, and certainly Data would never have intended to create a situation where his own code completely overwrites B4 and creates a replica Data.
A subplot removed from
Nemesis and left on the cutting room floor was Data's disappointment with B4's continuing inability to grow and develop. A number of scenes exploring this were filmed, but dropped. That's why he performs the engram swap: he intends to help B4 along a little bit, but emphatically
not to stop him from being whatever it is he turns out to be. This is also why Data gets so ROYALLY PISSED when B4 seems to betray them later in the movie, because in the context of those missing scenes, Data thinks the 'little push' he gave B4 earlier has led to another Lore.
As written (and indeed
as filmed) the Data/B4 subplot was much more complex than it was eventually presented as in the final cut. Ultimately that was down to the director of
Nemesis, Stuart Baird, who decided that he didn't like those scenes and so he cut nearly all of them out of the picture.
In the end it basically just comes down to my own personal opinion on the matter. I don't think Data would have ever intended for his personality to overwrite B4, and I do tend to hold the post-
Nemesis pool of writers accountable for doing something morally dubious (in order to bring back Data) without really exploring the consequences of that. The trouble is really that everybody just goes 'Yay, Data's back!' without ever looking at the wider issue of
how he came back, or what it means.
