Should roboticists (those who make robots) avoid making robots that think and feel like humans?

Robots shouldn't be made like humans because they would feel just like us and if some day they would find out they not humans and try to destroy the human planet.

Is there something about humans that robots will never possess? If so, what is it?

There is something that a robot will never posses it a brain they will never get a brain because they are mechanical an that is mostly wires and that is not a human brain.
