Fake News : An awesome story about the curse of discovery

It's the year 2033.
A team of four scientists discovers a substance in the blood of newts that obviously generates empathy. Its name is Empathol. The antidote is salt, which, consumed in large quantities, turns people into egoists. The discovery makes its way into the public arena and becomes a fashion drug among the powerful who abuse Empathol for manipulating people. The four researchers eventually fall victim to their own discovery. But one day, this nightmare ends - almost natural.
