Sense & Right

Take a moment and ponder over this.
Is doing the right thing equivalent to doing the sensible thing?
It makes sense that doing it right would be also be the sensible choice.
However, is it the case?
Is it really true that doing the sensible thing means making the right choice? Or
It it more true in doing the right thing as it is sensible?
In reality, doing the sensible thing may not be the right thing.
Neither doing the right thing would result in a sensible ending.
I'm torn between being right and being sensible.
I'm losing my sanity slowly.............................
Any clues? Help!
