To be able to have the thought, "Should I poison the tapeworm or shouldn't I?" you'd need to be someone who is capable of intentionally killing a living being. But in his discourse to Sutavan the wanderer (AN 9.7) the Buddha gives depriving a living being of life as the first of the nine actions that an arahant is not capable of doing.
