I originally thought Jessie Pinkman was an ESTP as well. However, later in the seasons I tended to see this strong Fi conviction in him. For instance, when the gang-bangers killed the little kid Thomas, there was this burning Fi conviction to avenge his death. Also, when it was discovered that Walt was the one that poisoned Brock, Jessie Pinkman went crazy Fi and turned on Walt and everything because he believed that it was the right thing to do.
However, I personally believe that the best example of Pinkman's Fi was when he just had this overwhelming Fi conviction that what he was doing was morally wrong. He literally went crazy and to try to appease his Fi he literally threw money out of the window because he believed the money was "blood money" and was mentally haunted by the fact that the money hurt so many lives to try to get it. This just seemed Fi as fuck to me.
Anyway, I don't really see that same moral conviction in Hank, and I tend to always see that in the FP types. I personally believe Hank to be an 8w7 as well, and one could say that the reason you don't see that Fi in Hank like the other ESFP's, is because he is an 8w7 and they don't look like the typical ESFP. However, a while back I was having a debate with soneone as to whether the character Tony Montana from "Scarface" is actually an ESFP as opposed to an ESTP. Scarface I believe is an 8w7 as well, but with Scarface, I believe that I could actually buy him as an ESFP. The character looks very much like a typical ESTP on the outside, but later in the movie he has this crazy Fi conviction not to blow up the kids and wife in the car when he is doing a mission for Sosa. Now to me this looked Fi as fuck. The bottom line is I just don't see this Fi conviction in Hank like I see in the other ESFP types.
