Is the Cobra effect story true or is it a racist British/Western trope “Look how devious and greedy the Indians/natives are, even when we are trying to make their lives better?”
Can you really breed Indian cobras in a home in captivity? Cobras are very good hunters and trying to keep them confined (remember how they are freed at the end of the story) and feed a growing population yourself is likely to take some time and effort, perhaps money that might not be worth the bounty?
