The assessment of whether the trade-off was worth it largely depends on one's perspective on governance, security, and personal freedoms.
A. Yes: One could argue that Chandragupta's effective organization and surveillance helped maintain order, prevent crime, and ensure loyalty among his subjects. It allowed for a strong and stable empire, which could lead to economic prosperity and security.
B. No: Conversely, one might argue that spying on subjects infringes on personal freedoms and privacy, creating a culture of fear and mistrust. The moral implications of such surveillance could outweigh the benefits of order and stability.
Ultimately, the answer may vary depending on the values and priorities of the individual assessing the situation.
