As a divine being, every moment of every day people are praying to you, seeking your mercy. Aside from offering you their faith and devotion, they also bring to you an endless stream of negative emotions.
Some are bullied and seek the divine spirit's protection to take revenge, some have lost friends and family to death and wish desperately for their resurrection, while others, having earned a silver coin, greedily wish to earn ten and pray for the demise of their peers.
Despair, resentment, pain, sorrow, and greed—each Divine Spirit receives, in fact, an overwhelming amount of these negative emotions, collectively referred to as Sinful Thoughts.
When Ange manifested them, it resulted in the legendary Spirits of Sinful Thoughts.
Even Anthony, who was quite worldly, had never seen a Spirit of Sinful Thoughts before. The manifestation of such a belief, filled with negative emotions, could drive normal beings insane or drastically alter their disposition.
