Leanbull probably held the citizens hostage and forced Weevil to surrender
Does it mean that in addition to being in a numerical advantage as shown on the last page vs Edward Weevil, GB also tried other means? Given his nature, it is plausible for him to do this kind of thing, even without caring about the lives of citizens. We have seen him justify all his atrocities by saying it is in the name of justice. LMAOOOO
Even if it is in the name of justice, it is not correct because it violates the basic moral principles of respect for life and human dignity. Justice should be achieved through fair means, and not by causing unnecessary harm to innocent people. Furthermore, hurting innocent civilians can have long-term consequences, such as increasing hostility and violence, and may even be counterproductive to the ultimate goal of achieving justice (creating a cycle of hate that we are already familiar with the Naruto stuttering about this).
The admirals are only caricatures of villains.
