The reason people connect Fi with ethics is because as a judging function, it weighs different factors including our feelings in order to evaluate the world and act in the way that feels "right." To make ethical decisions you have to use your Fi since answering questions like "Should we use underage siblings of ill children as organ donors?"or "Should I buy free range or conventionally raised meat?" requires a holistic view of all the elements involved, not just how images of animals in small cages make you feel, or how you'd feel if you were dying of leukemia and your little sister wouldn't give you a bone marrow transplant. Using our Fi we look inward at our gut reaction first, then our catalogue of past experiences in life, multiple possible outcomes of various decisions (my Ne feeding Fi), and what society says is right (sometimes, not always) and choose based on what allows us to maintain our inner harmony. You can still have uncomfortable feelings even if you're doing the "right" thing.
As a example, I enjoyed spending time with a man who had a girlfriend and started to fall for him, getting a vibe that the feeling was mutual but I ended our friendship because it disrupted my inner piece even though he evoked pleasurable feelings within me. That was Fi acting ethically.
Fe does this too although I'm still not sure how. Fi tends to be associated with ethical behavior I think because it is more noticeable since Fi users don't prioritize harmony with the world around them. Been puzzling over whether stuff like the Holocaust or the enslavement of blacks happens due to the majority of people in the world being Fe users or whether use of Fi or Fe has no connection with socially acceptable unethical behavior hmm. Just musing.
Interesting... lol
Blue seems like Fi ethical analysis. Seriously does look just like Ti analysis, except in terms of ethics. (again, idk if ethics is the right word)
Red:
Alternate Fe perspective just in case you were curious...
Most Fe users, when in this position, would consider the perspectives of the
girlfriend who would probably be affected most if anything happened
, and the Self last. A balancing act is best, and usually occurs with healthy Fe users.
Strong/healthy Fe users could/would care less about inner emotional peace, than they would about handling the
situation in external reality ethically in order to make sure everyone is ends up okay (which would be our idea of attaining peace... in the environment, where our feelings are/flow).
In a complicated situation: I personally wouldn't consider justifying to the self the actions that would be required that would allow the self to feel better, but rather focus on justifying to others what the best decision would be for everyone to walk away as safely as possible.
"You can still have uncomfortable feelings even if you're doing the "right" thing."
Yes. This can still happen with Fe. But letting someone know that you're feeling bad might inspire guilt in them, so with Fe I'd probably wanna refrain from saying anything (Lol). Actually, it's pretty easy for most Fe users to shut emotions out when the goal is to
prevent another from feeling bad because of showing them those emotions.
Hope that provides some insight, lol
