So, Dr. Faustus is an embodiment of curiosity gone wild. His blase attitude towards humanistic science is, however, some kind of a scientific decadence: he casts away philosophy and law, to embrace magic, as a relic of medieval obsession over mysticism. In this regard, he is a subversion of the Renaissance Man. He thinks he has already learned all there was to learn about this world, so now he yearns for another kind of knowledge - esoteric, otherworldly, knowledge that isn't exactly a knowledge because you don't have to study long and hard for it, you just have to sell your soul to Lucifer.
I believe the genre is Action and Adventure
The sub genre is Westerns
I’d go with “Lonely and homesick for his village and friends in Mexico”
