Why does the text imply it was necessary for the Spartans to terrorrize the heltos.?

The text implies that it was necessary for the Spartans to terrorize the helots to maintain control over their population and ensure the stability of their society. The helots, being a large and oppressed group, posed a potential threat to Spartan authority; thus, instilling fear was a strategy to prevent rebellion and dissent. This oppressive tactic allowed Spartans to focus on their military endeavors without the constant worry of internal uprisings. Ultimately, the terrorization of helots served as a means of reinforcing Spartan dominance and societal order.
