The theme of power
The protagonist, Paul Atreides, is the Muad'Dib, the ruler of a powerful jihad and universe. In addition, Paul has the power to see the future. However, despite being a powerful figure in society, Paul feels feeble because he cannot control what he sees. For instance, Paul can see the danger that is about to happen, but he cannot control it. In the novel Dune Messiah, the author illustrates that power is not everything because those in power cannot control every situation.
Mixing religion with government powers
The novel explores the dangers of mixing religion and politics. According to the author, spiritual leaders should stick to religious convictions. However, the people of Arrakis choose Paul as their ruler. Paul is a religious figure, and when he gets into office, he establishes a jihadist wing, which spikes corruption and extremism. Paul later realizes that the people he appointed to head the jihad are plotting to kick him out of power. Therefore, Paul needs help to balance government business and the pressure of religion. Towards the novel's end, Paul regrets combining religion with government operations. In other words, Paul suggests that religious leaders should not mix with government forces.
Culpability and desire
The theme of guilt and desire is prevalent throughout the novel. After ruling the universe for 12 years, Paul feels vulnerable and blames himself for government failures. Since Paul is the messiah, he cannot escape his responsibility, and the people of the universe look up to him. In his dreams, Paul foresees Chani influencing his wife to conspire against him. True to his vision, Paul’s wife works with Chani to feed the people contraceptives to fulfill Bene’s orders. Bene is among the leaders conspiring to withdraw Paul. Paul feels guilty that he cannot control the evils plotted against him and the universe.
