He along with his brother used to love Humanity until Salem manipulated and turned them against the Gods. He considered the world that would become known as Remnant to be a beautiful experiment. He could never detach himself completely from his grand design, as he tasked Ozma with the mission to redeem mankind, displaying his continued devotion to his creations in spite of his profound disappointment in them.
The God was overprotective of Humanity, blessing them whenever the his brother plagued them.
The God of Light is the older brother of the God of Darkness. Despite their differences, and his brother's own hostility towards him, he cares for his brother deeply. He even attempted to tell him the truth about Salem. In turn, the God of Darkness came to his brother's side during Salem's rebellion.
Despite each brother thinking they were the original deity, the God of Light took on the role of the elder sibling as the God of Darkness mimicked his actions. Though the two frequently butted heads due to ideological differences, they only ever felt complete when with one another.
When the God of Light first met Salem, he refuses to revive her deceased lover and tells her that she should move on. The God of Light along with his brother cursed Salem for her selfish and arrogant desire to revive Ozma. He initially felt pity for the grieving woman, but his sympathy did not override his imperative to maintain order.
Following Humanity’s destruction and before leaving Remnant, the God of Light hoped that Salem could still learn from her mistakes despite everything that happened, showing that he still felt a sense of sympathy towards her.
After his departure from Remnant, the God of Light talks to Ozma “between realms” and gives him the task to bring peace to Humanity. To achieve this, he endowed him with the ability to reincarnate. He also created the four Relics, objects when brought together would summon him and his brother back to Remnant. The God of Light appeared to respect Ozma when choosing him for this task, likely due to his role as a catalyst for what had happened.
