Since the title is rather open - ended, the main characters could be a diverse group. It might include people who are haunted by the idea of the dead not being able to complain. There could be family members of the deceased who are left to deal with unresolved issues. It could also feature characters who are in some way related to death, like undertakers or those who work in morgues, and they might be grappling with the silence of the dead.
Without having read the actual 'dead men can't complain and other stories', it's hard to say for certain. However, one could assume that there are characters who are in a state of grief or guilt. Grief because they have lost someone who can't complain or interact anymore, and guilt perhaps if they were involved in some way in the situation that led to the death. There might also be characters who are investigators or researchers trying to understand the concept of the dead not being able to complain, like philosophers or forensic experts.
The main themes might revolve around the contrast between the living and the dead. In 'dead men can't complain and other stories', it could show how the living have the ability to speak up, while the dead are in a state of silence. It may also deal with the mystery surrounding death, as we can only guess what the dead would complain about if they could. There could be themes of regret as well, thinking about things the dead might have left unsaid or undone.
