A fun quote from a letter Franklin wrote to a doctor that is cited in Losurdo's Liberalism:

Half the lives you save are not worth saving, as being useless; and almost the other half ought not to be saved, as being mischievous. Does your conscience never hint to you the impiety of being in constant warfare against the plans of Providence?

So not something he did, but more a look into his frame of mind. He really didn't care for the poor.
