I think that's a stretch - it would be like saying war is really a good thing because of the (possibly good) ending side effects.

If I may recall the relevant operetta on HN:

CANDIDE:

Objection! What about war?

PANGLOSS:

War!

Though war may seem a bloody curse

It is a blessing in reverse

When canon roar -- Both rich and poor

By danger are united!

(Till every wrong is righted!)

Philosophers make evident

The point that I have cited

'Tis war makes equal -- as it were --

The noble and the commoner

Thus war improves relations!

(Pangloss tries to justify the apparent imperfections of the world by claiming that it is optimal among all possible worlds. It must be the best possible world, because it was created by an all powerful/knowing God, who would not choose to create an imperfect world if a better world could be known to him.) http://en.wikipedia.org/wiki/Candide
