Hello! I hope this answer helps you. Based on the lines, which talk about this person’s country, it’s people, and this person’s relationships. Particularly when the person was “those that I fight I do not hate” make me think that this person is perhaps a soldier maybe craving death, or being curious about it. The mood of the poem is very lonely, as you can see this person doesn’t care about anyone, and they think of their life as a waste of breath.
