Which line in these excerpts best explains how war changes soldiers?
You’ve heard me, scornful, harsh, and discontented,
Mocking and loathing War: you’ve asked me why
Of my old, silly sweetness I’ve repented—
My ecstasies changed to an ugly cry.
(Siegfried Sassoon, “Poet as Hero”)

If in some smothering dreams you too could pace
Behind the wagon that we flung him in,
And watch the white eyes writhing in his face,
His hanging face, like a devil's sick of sin;
If you could hear, at every jolt, the blood
Come gargling from the froth-corrupted lungs,
Obscene as cancer, bitter as the cud
Of vile, incurable sores on innocent tongues
(Wilfred Owen, “Dulce Et Decorum Est”)
