Ohgi was the leader of the rag-tag rebel group, and then Zero came along and made that group into a strong organization, The Black Knights, taking the mantle of leader. Both were leaders but which one lead better? There are 7 virtues of a good leader according to goodleader.com: ethics, self-control, generosity, diligence, patience, compassion, and humility.
- Ethics- don’t have a bad reputation. Zero’s various decisions have come under question. For example, the secret mission to attack the Geass Order. None of the Black Knight’s knew the reason for the attack so when the truth came out that the attack was a massacre instead of a reconnaissance mission as they were lead on to believe, they were shocked and that caused distrust in Zero. Also there is the fact that they never trust him because he wears a mask. We see that the only ones who ever fully trust Zero are the ones who know his true identity and have accepted it. On the other hand, Oghi has nothing to hide. He wears no mask so he is easily trusted. This is the main reason why Oghi is second-in-command.
- Self-Control- follow the rules. Zero is a terrorist and never follows the rules. He manipulates and kills people to get what he wants. He believes that the only way to get what you want is to circumvent the rules and plow straight through to the solution without heed to the repercussions.
- Generosity- think about what is best for others. Zero never seems to care about what his subordinates think or feel. He is the supreme leader of the Black Knights and tries not to form any personal attachments or relationships with his followers. His job is to create strategies and preform miracles. Ohgi is the one who is more willing to say “good job”.
- Diligence- work hard, pay attention to detail, good time management and resourceful. This is where Zero shines over Ohgi. He took a lot of effort to build the Black Knights into a formidable army that can fight Britannia. From various chess games played throughout the series (nobleman in episode 1 of R1 and R2, Mao, and Schneizel), and planning out battle strategies you can see that he pays attention to detail. He has exhibits the intelligence to use his geass to get what he needs. For example, the car that Zero procured in episode 8 of R1. Ohgi is not as intelligent or resourceful a Zero but he is a hard worker, willing to take command of the rebel group when its previous leader died.
- Patience- view both sides of argument and solve conflicts peacefully. Zero does not solve conflicts peacefully; he either used his geass to make the opposer agree with him or he uses his military power to forcefully get others to onto his side.
- Compassion- offering friendship, kindness and sympathy to others. Zero doesn’t do anything unless it would benefit him or the Black Knights image. He tries to keep his distance so he never creates meaningful relationships with his followers but he ends up having a somewhat romantic relationship with his Ace Knightmare pilot Kallen and even promises to save her no matter what when she is captured by Britannia. Ohgi looks out for his team (worries about Kallen in place of her deceased brother).
- Humility- not flaunting your position. Zero boasts about his position and intelligence. He is the son of the emperor and is obviously proud of it reminded others by saying, “Lelouch vi Britannia commands you…” He gambles by playing high-stakes chess with rich nobles. Ohgi is much more humble, thinking of himself as an ordinary person in a crowd of geniuses.
Even though Ohgi seems like the best leader, Zero is better because he produces results and creates “miracles”. What is the point of fighting something if you never win? Under Ohgi’s leadership, the rebel group never amounted to much, but under Zeros guidance, they started making an impact in history. Zero is the brains and strength of the group, the star, while Ohgi is the backstage stagehand, important, but never in the spotlight.
