Do They Deserve It?

After seeing Twilight Zone 2, I couldn't really decide wheather they deserved their punishment. There was two characters. They were opponents in the war, yet they were the two only survivers of the town. First the american beats her down and takes her food, but then he comes back and wakes her up, feeds her and introduces. She seems german and therefore does not understand him. To resume quickly, he finds a wedding dress and gives it to her. She was about to put it on when she sees pictures of american war propaganda and decides to shoot the man. She misses, and he stands up and leaves. Days after not seeing her, he gets ready to leave, and does so. He is about to leave when she appears with the dress on, and they are in love and leave together.

To begin with, I interpreted the punishment in the following way: The couple was opposite in war, and they are forced to live together. If this is their punishment, then it is not poetic justice. It is not poetic justice because it is no great punishment, they become a happy couple and leave the town together. They share their food, shave together and stay together for a while. They get mad for a while but then they hook up and get together. Again, they are not punished! They deserved to die, for what I interpred. They could have killed hundredths of people and they just end up in love. It was not punishments. It is not poetic justice.
