INxPs are very passive by nature, as Informatives and philosophical types; we are far more likely speculate on the nature of existence (its inherent functional or moral nature) as a detached observer. And then when we are not functioning properly, we withdraw further. The battleground as others have said is often internal -- a war of ideas or a war of morals that we test within ourselves.
Note that Andrew from "Chronicle" is motivated by a long period of injustice in his life, resulting in a lot of internalized rage/bittnerness, and so when he finally has power, he lashes out. It's something that happened to him and stirred him into an internal frenzy, he's reacting. I think INFP is a plausible read; if he had grown up in an environment that didn't foster rage, he likely wouldn't be destructive and "right the wrongs" in the sadistic way he does. He's kind of an anti-hero in the movie -- abused child becoming the abuser rather than the hero he might have been. He also becomes an embodiment of the "truth" he has been learning in his life (about being an apex predator); my experience as an INP is that I make myself my own "experiment" per se to learn/express truth, and here Andrew is reflecting back his own life experience that he has been letting percolate inside.
