@oristarA,
When something is Immoral, it does not mean that it is NOT necessary.
Something Immoral can be necessary.
This example using the Soviet Union is a fine example of this.
They WERE aware it was immoral.
It was a politically reasonable maneuver used to ensure national security.
It was undertaken for the Greater-Good.
Therefor, if you reflect on my statements you will understand my contribution to this discussion.
(* I notice that you often ask questions about grammar. The word "Sound" can be used in the same way "reasonable" can. [example: It was a politically sound maneuver.])
