I think that the last scene of the play is fairly important. Consider the sad and pathetic state of Blanche when she utters the line, "I have always depended on the kindness of strangers." It is a profoundly sad ending because Blanche's words belie the condition of the word in which she finds herself. Her victimization at the hands of the world, a setting that does not even seem to stop for a moment at the cruelty Blanche suffers, is a statement that Williams renders about the condition in which human beings live. The poker game goes on, Stella recognizes that she might have made a mistake, but is soothed by Stanley. The idea that "life will continue" despite the fact that Blanche was raped and then institutionalized through manipulation by others is an ending that reflects the lack of redemption present in the world. When one searches for why there is cruelty or why there is such a preponderance of evil in the world, the last scene might go very far in suggesting why the modern setting is constructed in the manner it is.
