So the analysis is:
Narad was afraid of being called fool.
Queens were not ready to suffer humiliation from people. And they were also not ready to suffer in hell to make Lord happy.
Maids of Vrindavan were not at all worried about the consequences of their actions other than that their action would bring comfort to their beloved. They were also not worried about any defamation. All that they wanted was to make Lord happy.
This is the difference in business Love and selfless love. Selfish love not worthy of consideration
An important aspect of selfless love is presence of Radha. As Krishn is happiness incarnate, Radha is Love incarnate. The Love that we are seeking is personalized in the form of Radha and therefore supporters of selfless love worship Radha-Krishn (Love & Happiness) together.
