Introverted Intuition (Ni): Walt has a singular goal that always holds onto - to provide for his family, before he dies from lung cancer. He’ll do anything to achieve this goal, even if it involves morally reprehensible actions. No matter the trouble he endures throughout the series, he continues to return to his meth lab, ready to earn more money for his family.
Extroverted Thinking (Te): When he needs to accomplish a goal, Walt will plan everything out accordingly, and gets angered when there are deviations in his plan. He orders Jesse around like a subordinate, and keeps tight control over his many dealers.
Introverted Feeling (Fi): Though he rarely is very expressive, Walt feels greatly, and does not like going against his ideals or principles. When Elliot and Gretchen offer to pay off his cancer treatments, he outright refuses, bitter at them for stealing his hard work and achievements. He demands respect, that people “Say his name”. Whenever his pride is violated, he will react violently.
Extroverted Sensing (Se): Even though he’s much more of a planner then a doer, Walt grows to enjoy his reckless new lifestyle. He gets a thrill out of the danger of being in the drug business, and even continues, after his cancer goes into remission.
