Which wors best sums up the way the speaker in the poem 'Futility' feels?

The meaning of the title, then, is the futility of trying to understand how nature could create life but stand by as it is laid to waste. As they move their dead comrade into the sun, the speaker wonders why the sun, which restores life, can't restore his friend:

"Are limbs so dear-achieved, are sides

Full-nerved,—still warm,—too hard to stir?"
