Since, it is not going to benefit any of us, it should not be done.

I heard the following statement from many people in many different situations.

Since, it is not going to benefit any of us, it should not be done. 

My response used to be, what are you going to lose, if it is done? Since I get some benefit out of it, this needs to be done. If you are going to lose anything out of it, then we will discuss that and see how we can resolve that. 

Of course, Till now, I could never convince the people who said that. [Eventhough they were not going to lose anything.]
