Angels in America Act II scenes 7-10/Donne: His Picture

In Angels in America act II scenes 7-10 and Donne's poem it seems similar. Louis is aware of his own sickness so he doesn't care about his health anymore. However he wants Joe to be healthy and suggest he doesn't eat the hot dog. In the poem, Donne is also aware of his sickness and death, so whoever he is speaking too, it seems like he is guiding that person to not be like him, and to be better.
