Fatui Harbingers' experiment

Dottore's unfettered research towards creating a god, or elevating humans to the level of gods, left him ostracized from mainstream society but paved the way for him to become one of the most powerful members of the Eleven Fatui Harbingers, with strength comparable to the gods'. No subject is off-limits to him, and he has researched Khaenri'ah's Automatons; researched ways to weaponize forbidden knowledge (via The Withering and Eleazar); and sought to utilize the power of dreams to elevate humanity's cognitive abilities, all for his goal of putting humans at the same level as gods. This ambition is likely the reason why Pantalone, who seeks to "overthrow the natural imbalance between gods and humans," works closely with Dottore.

Pursuing his research interests surpasses any of Dottore's moral scruples, which makes him an effective researcher but also often comes at the detriment of others. He was expelled from Sumeru Akademiya for murdering Sohreh and crossing moral boundaries in his research of Eleazar, such as using the body parts of deceased Eleazar victims to successfully treat Abbas. Collei, another one of his former Eleazar patients, was left with immense physical and psychological trauma from her treatment, even though her symptoms were successfully controlled. Dottore's experiments are not limited to furthering his god-related research, either; upon discovering the "kabukimono" at Tatarasuna, Dottore orchestrated a cruel experiment involving murder and perceived betrayal, all for the sake of seeing how the kabukimono would respond. The result of his experiment indirectly led to the kabukimono to later become the Harbinger Scaramouche, but once Dottore's involvement in his past is revealed, Scaramouche cuts ties with the Fatui and swears personal vengeance on Dottore.

Dottore, a character in Genshin Impact, is characterized by his obsession with scientific advancement and disregard for human life, making him a mad scientist figure. He is driven by a relentless thirst for knowledge and experimentation, often willing to use others as subjects in his research, even if it means sacrificing their well-being.
