Should you always add negative feedback?

Yes, positive feedback with enough gain will cause instability or oscillation. But some nice oscillators or signal generators are made with pos. feedback.
So, no you shouldn't ALWAYS use negative feedback, especially if you want to make an oscillator.

I always delivered feedback where needed, in the form of a sandwich, for positive feedbacks, but where I needed to keep the perosns feet on the ground, they'd get good feedback-negative (have to find something, no one's perfect- good feedback, and where the opposite was needed, they got the s**t sandwich, negative-positive (so they didnt feel too peed off- negative feedback....

Iv'e never heard of an instable ebayer just coz he got too much positive feedback.
(that was a joke btw)

actually no. It can saturate and become stable. This is used in al buffer chips.. or u741s or any other chip/.
