Lord Rama killed Bali secretly because Bali had a boon that any enemy became powerless in front of him. For this reason, it was impossible to wage war directly on Bali. Ram resorted to this strategy to protect the religion and to get justice for Sugriva. Bali questions Rama on his deathbed, and Rama tells him that he did it to establish righteousness and justice. Bali accepted this decision of Ram and repented for his mistakes
