Did they plan on Sephiroth becoming emotionally and mentally unstable?
No, they just wanted him as a tool to find the Promised Land and also fight as their strongest SOLDIER. Sephiroth stumbled over the partially false documents after concluding that he was not just an extraordinary human. Actually after that Sephiroth himself became almost completely emotionless. Very similiar to JENOVA which is also emotionless. Really the only emotion Sephiroth shows is his joy of showing his over-poweredness which is triggered through the inner grudge he holds against Cloud, a mere ShinRa grunt, for embarassing him by actually defeating him, the strongest of all.
