Law Vs Chaos in the context of SMT 4's Apocalyptic Tokyo (Pro is law Con is Chaos)

Context : Essentially the world was thrown into a state of fear by 'demons' appearing in the cities. Countries lost control, leaders went mad and the world was ultimately very afraid. For this reason, bombs were launched off and many countries tried to throw blame all around. Tokyo realized this would soon mean the end of the world, and managed to create a dome that surrounded the entirety of Tokyo, and would then protect the inhabitants from the external threats. However, this did not protect them from the demonic uprising. The demons were very prevalent and made many changes to the culture/workings of tokyo. This lasted for 20 years. People were dying, and had to form underground bases. They had to hide, and fight just to survive. They lost most of their large scale technology, and lost any proper form of government or organization. For this reason, people elected to escape and see how the outside world was. The only weakness in the dome was at the top, through a long tower. They climbed and eventually dug, and managed to make their way to the land above. But what they found was that other humans had already done this, and there was a land known as Mikado. In Mikado people had found the love of god, and lived for the most part peacefully. There was some corruption, with a lower and higher class system that segregated the land. But they were ultimately safe from the demons, and protected by the angels. But they did not condone those who had been 'tainted' by Tokyo to live in mikado, it was essentially a safe haven for only a select few, rather than for humanity itself. So the main character Flynn, was given a few choices of how to proceed. He was born in Mikado, but he went down to Tokyo. Being a messiah of sorts, sent to tokyo with intention, he would be allowed to return and be treated as a citizen of Mikado rather than an 'unclean one' of Tokyo. Merkabah, the angel proposes the way of Law, to ultimately make the ways of mikado the ways of the world. They would eliminate those in Tokyo, expand gods control and create a safe world where people had to follow strict codes resulting in a loss of freedom and in most cases pleasure. However, they would be safe. They would be protected. They would know love and comfort. Lucifer however, did not feel this was just. It was not in favor of humanity, rather a select few. But there many ruling factions in tokyo, and the land was going to hell. People were afraid. People were controlling. What the people needed was a new leader, but in the current situation too many people had bonded together and attempted to control tokyo for their own selfish purposes. So lucifer instead proposed to increase the amount of demons exponentially, forcing humanity to evolve and ultimately find a new king through the chaos, Flynn. Flynn must either side with Merkabah, forsaking the people of tokyo and bringing peace through Mikado, or create a temporary chaos, inciting war and death, but ultimately leading towards him being the new King. As king, he would be just, and un-corrupt, however many people may suffer and die before then. My argument is simple. Merkabah's route would desolate the entirety of Tokyo, while Lucifers only causes major damages and suffering to tokyo. But both routes ultimately lead to a world controlled by a new king. Merkabahs rule however has already shown faults, while Flynn can learn from these and aim to create a far superior world. The only major downsides would be the pain/emotional suffering , as Merkabah would finish his opponents off instantly, rather than making them suffer like the demons would. But I feel that the sacrifices of these few grant the survivors enough positive changes that their deaths are not in vain. Ultimately, Flynn must Either Kill Merkabah and follow lucifer, or Kill Lucifer and follow Merkabah. I argue that he should follow Lucifer.
