On the one hand I am for the killer robots because they can be used as (enlever le "a") soldiers  

On the other hand I'm against because the world will be filled with robots, they would force more humans.

Also the robots are very expensive. It is possible to imagine that robots will beable to take over (enlever le "of") the humans beings.

They will have an impression that the human beings are useless.
