Castiel: INFP [Supernatural]
Dominant Function, Introverted Feeling, Fi: Castiel is a very different angel from the rest and this comes from being an Fi dominant with inferior Te. (More on inferior Te below). Fi is a very subjective, individualistic, and experiential function. Castiel is the rebel angel because his first instinct is to judge from his own experiences. He doesn’t obey or follow the laws of the angels first. He will if he agrees with them, but we see he clearly doesn’t. He changes his mind and adapts as he experiences new things, new sensations, new experiences in general with the Winchester brothers. What seems right before he starts to question. It simply doesn’t “feel right” to him anymore. Hence, the start of the relationship he has with the Winchester brothers in their anarchy against mythical forces.
Fi focuses on fundamental human values and are prone to more of an idealism than the moral dealings of Ti. Fi for Castiel is seen in how he deals differently with each individual human, how one human doing a good thing is beautiful to him. He doesn’t adhere to Angel rules and principles of how to judge and deal with humans and being on earth. He handles each situation as unique and judges in the moment. Fi has an emphasis on that free will. The very thing that separates him from the rest of the angels. He doesn’t think Dean and Sam should conform to the plans of the angels, but can make their own path. He becomes a defender of free will for everyone, including himself.
Fi being prone to idealism is also very prone to self doubt as a result. This is what centers on the beginning of his character arc. As an angel his Fi gave him this ideal of how things should be instead of how things are. When he finally is outside of his own head, his own romance of how things are on Earth and he lives in it helping the Winchesters these feelings of doubt set in for him. Life on earth and the angels do not uphold the ideals Castiel held close to his heart. He isn’t seeing reality reflecting his inner world. This can become disastrous for an INFP like Castiel who can’t reconcile with his inferior function of Extraverted Thinking. This combination leads to the darker path he takes.
Auxiliary Function, Extraverted Intuition, Ne: This function helps promote a healthier Fi outlook as it grounds Castiel in the objective experiences in the outer world beyond his Fi inner world of personal and circumstantial judgments. Se can work in much the same way for ISFPs. This secondary function helps balance out an IFP so they are not stuck in doubt, disappointment, and dissatisfaction that comes with being stuck in an inner world of Fi. What Ne specifically focuses on are more impression of experiences rather than the concrete experience. Castiel with Ne is trying to unpuzzle a deeper meaning in the world with Ne, but through his Fi lens.
This is what makes Castiel feel so lost. His Fi has led him to question and doubt the world as he conceived it before, he is questioning the authorities of the universe, especially as God is real big on one way conversations. If his Fi judgments are to be trusted and all the angels are wrong in their bringing on the apocalypse and using the Winchester brothers, then what is the meaning of angels in the first place. What is Castiel’s role in the big picture of the universe, what is the role of the Winchesters? What is the right thing to do? He is left looking for meaning and patterns that make sense of his Fi judgments.
Unlike an Ni-Fe combo that looks to help and understand people in a bigger picture, looking at society as a whole, Fi-Ne focuses on helping those who have fallen through the cracks of society and the system. Castiel feels for the demons, for the humans, for everyone his angel brothers and sisters seem to underestimate and dismiss. He finds meaning in helping those who are left behind.
Tertiary Function, Introverted Sensing, Si: Si is a very personal function that takes in concrete information that works desperately from society and any system therein. This can be a problem as Fi also works in a very personal and subjective form. So without proper use of Ne and Te to ground an INFP in the objective outer world, Castiel becomes rather unhealthy as he isolates himself and doesn’t use his Ne when he doesn’t get the answers he wants. He picks and chooses the Si concrete forms of information that fit his already made Fi judgments. This is what motivates his taking on the position of God and leading the angels. He starts to distribute divine punishment on humans. He works with the information that conforms to his judgments instead of using Ne to see outside of his own perspective.
Inferior Function, Extraverted Thinking, Te: As the inferior function Te is what irks Castiel the most, but what influences him just as much. He finds Te judgments, those based on proven principles to create rules and order to the world overall to be cold and heartless. They miss the individual experiences of each unique person. Castiel finds this mode of thinking to be incredibly imperfect with his Fi priorities. Order and structure should not come above individual freedom and happiness, no matter the greater purpose. Te structure tries to pin Castiel into a very specific role as an Angel, but his Fi challenges this pigeonholing. Castiel doesn’t see himself as being definable in this way. He is an exception. So he tries to erase this boundary imposed upon him by the angels, demons, and anyone else who wants to tell him who he is.
However, as much as this thinking irks him, the more he pushes it away and does not see this function inside himself the more Te impulses show themselves within his personality and way of going about things. Because of his Fi he finds the system to be corrupt, morally wrong, and leaving too many people behind. This is when he tries to take on being God. However, he starts imposing his own Te order on others. He becomes strict and cold while being motivated by Fi.
