Answer:
Irony.
Step-by-step explanation:
Stephen Crane's poem "War Is Kind" is an ironic take on the devastating and savagery of wars. The poem presents the emotional as well as the physical torture and suffering that war brings upon those who fall on 'his hands'.
In stating "war is kind" numerous times, the poet seems to sarcastically and ironically talk about the evils and misfortunes that war brings. He askes the maiden, the babe, and the mother, not to weep, for "war is kind" and it has taken their loved ones. This is ironic as the poem talks of death as something that the ones left behind must be happy about when their loved ones die during the war.
Thus, the correct answer is irony.
