In Larry McMurtry's "Lonesome Dove," Augustus reflects on the sadness of loss, particularly the profound impact that the death of a person can have. He emphasizes that once life is gone, it cannot be regained, urging his son not to seek revenge for the loss he feels. Augustus understands that the consequences of such actions can lead to a never-ending cycle of violence.
Instead, he encourages his son to focus on the more pressing challenges at hand, implying that vengeance may not provide the closure or solution one hopes for. Augustus' own feelings hint at unresolved tensions, especially concerning a character named Blue Duck, indicating he has his own motives for revenge but recognizes that it may not be the best course of action.
