The poet's reason for using words like "kind" and "civility" to describe death is most likely to establish an atmosphere of cold, formal reserve that embodies death. These words personify Death in a non-threatening, gentle, and respectful manner, contrasting with more common frightening or harsh perceptions of death. The use of "kind" and "civility" suggests a peaceful, calm, and almost polite approach to the concept of dying, making the encounter with Death seem more like a courteous interaction than something to fear. This interpretation aligns with the literary device of personification often used in the poem "Because I could not stop for Death," where Death is depicted as a gentlemanly figure treating the speaker with respect and care, making the journey towards death seem leisurely and dignified rather than abrupt and terrifying. The poet may use these words to soften the idea of death and to evoke a sense of acceptance or inevitability that is accompanied by a certain grace.
