How we cite our quotes: (Paragraph)
Quote #4
And besides, it is not improbable that some scrupulous people might be apt to censure such a practice (although indeed very unjustly) as a little bordering upon cruelty, which, I confess, hath always been with me the strongest objection against any project, however well intended. (17)
Who are these scrupulous people? The narrator doesn't exactly seem like the type to object against cruelty.
Quote #5
Some persons of a desponding spirit are in great concern about that vast number of poor people who are aged, diseased, or maimed, and I have been desired to employ my thoughts what course may be taken to ease the nation of so grievous an encumbrance. (18)
The narrator suggests he's only one of many who are concerned about the old and sick. In real life, Swift was upset because no one was stepping up to help.
Quote #6
But I am not in the least pain upon that matter because it is very well known that they are every day dying and rotting by cold and famine, and filth and vermin, as fast as can be reasonably expected. (18)
Notice the shift in tone from the last quote. The narrator shows he can switch off concern and turn his attention to making money.
