Well done, but also morally justifiable?

Nevertheless me but the question arises
what should be communicated to the player by.
About: The our researchers and doctors could not?
It seems disrespectful to all mankind want a bit of infecting with a disease,
they then ultimately even kill.
Would it be one probably better to invert the whole, or to draw on an economic level,
by the player sells a product and developed (Advertising make etc.)
the whole of humanity with the product "infected" and as a business owner.
But just as a suggestion ...

Otherwise, however, all respect to the programmer,
because the game provides an increased level of difficulty,
which is still doable.
