Technology and Mankind

We invent a pill that cures. Then we make one to make us high. 

We invent a vehicle that can transport us back and forth to work and for family vacations. Then we realize we can use it to plow through a crowd of bystanders. 

We invent a flying machine that we can soar above the clouds as we travel to faraway lands. Then we discover it can be used to destroy skyscrapers. 

We invent how to split the atom and learn how to power cities.  Then we use the same technology to destroy an entire city with a single detonation. 

We invent a drone that can take aerial photos and deliver packages. Then we attach a weapon of war. 

We invent a 3-D printer to make medical devices, and prosthetic limbs. Then we install software in which we can print a gun. 

I am starting to see a pattern.
