So you work hard to keep that feedback gain under '1' in an amplifier and over '1' in an oscillator.
Technically an amplifier with a feedback mechanism can become an oscillator and if you break the feedback loop in an oscillator you end up with 'just' an amplifier.
To make this even more interesting: a negative feedback element in an amplifier will greatly enhance the frequency response at the expense of amplification (and will vastly reduce the chances of that amplifier turning into an oscillator).
