Do you think that we take the small things in life for granted. Take for instance, you holding on to an egg without breaking it, or how about closing your eyes and feel the breeze caress your face. Of course, we might think nothing much of those, but pause for a moment and reflect on how robots are. I suppose if they were capable of emotions, then they would certainly want to "kill" (hopefully not literally) to be able to have the sense of touch built-in.
