This poem by Shi reflects the author's ideological contradiction. Where is this contradiction reflected?

It is a contradiction of worrying about the country and the people. On the one hand, Du Fu believes that arresting people and recruiting soldiers can expand the scale of military camps, which is conducive to the expansion of the army and the victory of the war. On the other hand, conscription also means that countless families face the separation of their wives and children, which is contradiction. But this contradiction is unified in one point, which is Du Fu's accusation of war.
