So you're telling me a beaten child or dog isn't conditioned to feeling fear.

What, exactly do you think PTSD, c-PTSD, dissociative disorder, personality disorders and any number of other diagnoses are? They're certainly not innate.

Edit to add, do you still cry when your meals are delayed, or your stomach aches?

No. You've come to accept (you've been conditioned) and understand you will eat again, a discomfort will pass.
