I would not call war GOOD - I’d say necessary at times but never good. Until you’ve actually had to fight one it is easy to say that war is good. Take it from someone who was at one time eyebrow deep in war and killing and take it from me war should never be seen as good.
I believe it was General Sherman, during our Civil War, said “War is Hell!”
Many times he has been quoted; “War is Hell!” And we all know is the only good part about war, is winning it, and it coming to an end.”
But war is not Hell! Wars come and go, but hell is for all eternity!”
