As I recall, the bypass capacitor on the emitter resistor
is there to REDUCE the negative feedback that is the
result of increasing emitter current.

     (I remeber this one from college, back in the Dark Ages.)  The cap is there to bypass audio and higher freqs (AF+) to prevent said frequency variations from causing the operating point of the device to follow AF+ variations in current flowing through the emitter resistor.  The bypass cap essentially eliminates any AC fluctuations from destabilizing the opeating point.  FWIW.
