Philosopher and fangirl. Worst. Combination. Ever.
He actually says he's going to "respect his subjects". Now, what does he mean by that?what gives him the right to rule? power? the fact he killed Mundus? none of these things make him ruling humanity against their will ok. even if you argue it would help humanity through the demon invasion, it would only be for so long. in the end he will just be Mundus 2.0 perhaps not as deceitful but everyone answers to him and all opposed would be dealt with. all this is bad enough, if you also add the fact he regards humans as weak and overall useless you put a whole other issue into the mix. suddenly he is no longer a leader (who is equal to his subjects and lives to serve) but a lord of us ( who is superior and lives to be served). its all morally wrong.
Philosophically speaking, "respect" and "subjects" are two terms that are usually seen as opposites, as respect, in moral philosophy is meant as considering other people as morally equals. I'm not going to expand the analysis of the meaning of "moral equals" here, nor the POLITICAL effects that this MORAL problem may have, because it is a really complicated issue, which affects a series of terribly complex moral and political problems, that philosophers are still debating. (If someone is interested in this debate, I suggest to take a look at John Rawls' works).
Dante and Kat focused on the term "subjects", while Vergil's words could also be interpreted by emphasizing the term "respect". If we follow the second option, his words become less harsh. Is it wrong for a parent to educate his children? No, because they need to be taught that certain things are wrong or dangerous, as they don't know it themselves.
Is it wrong for a state to establish rules (for example, laws that defend freedom of speech)? Laws are necessary because we cannot just hope that all people would act righteously. A lot of people don't, even if such laws do exist.
Now, what if a good monarch establishes laws that protect human rights? Would it be so bad? Why do we think that it would probably be better if such laws are enforced by a democratic government?
My answer is: because we think that democratic processes are more likely to lead to better decisions. The assumption we are relying on is this: a confrontation between two ideas usually leads to a better solution that each of the starting ideas.
But that is not always so. There are particular conditions in which open debate is not the best solution; in dangerous situations that require swift action (war is an example) we need a leader to take decisions. Romans institutionalized this fact: in the years of the republic law established the possibility of appointing a dictator who was given all the powers for a limited period of time.
Now, my point is that, after Mundus' fall, we are faced with a situation that calls for a dictator.
The problem is what happens AFTER. After the emergency has passed, what could be Vergil's role? Would he accept to see his powers limited? Would he accept to be just a leader and not an absolute ruler?
My point is, WE DON'T KNOW. Dante didn't let him explain.
Moreover, even if right at the end of Mission 19 Vergil truly intended his role as that of a benevolent absolute ruler, maybe he could have come to change his idea as time passed, really becoming a good leader (he's an intelligent person, and intelligent people CAN come to realize their mistakes).
CONCLUSION
My point is that, by shutting him out from the very beginning, Dante once and for all closed the still existing possibility that Vergil could really be or become the leader (a guide, a good counsellor, but not and absolute ruler) humanity needed.
That's why, to quote temp-dsn's proposal, it would really be interesting to have a spin off that recounts the story FROM VERGIL'S POINT OF VIEW. Just to know what was really going on in his mind, apart from how he formulated his ideas in that particular confrontation with his brother.
Edit: as an afterthought, sorry for going all philosophical on you, but I'm a political philosophy student, and I couldn't really help myself, because these are issues that are very important to me.
