Oh, I'm definitely not attributing motive, rather, I'm using that argument to completely undercut any moral authority the Institute's 'save humanity' BS that they currently trot as justification for amoral Doctor Mengele experimentation.
If they were simply determined to live apart from the surface, there wouldn't be a problem, but they routinely screw with the surface to serve their own ends.Read enough of those old tapes, and you see several different viewpoints at work in the Institute over the years....some hostile toward the surface, some ambivalent, some completely apathetic. The "Speech" you give, that was crafted by Father, pretty much says that the (current) Institute has no interest in the surface.
This may be a good point, though they're evidently effective enough to use on regular combat missions. So what's the proving process like? At what point is that experimental weapon good enough to use to serve the purpose of all weapons, namely to bring victory, and with it, peace?Add to this, the fact that Synths are still pretty much in a Beta phase, and the Institute hasn't really made all that many of them, other than to replace the ones that keep going missing, or are destroyed while on surface "recon"...
