It took me a while to understand one thing

When Jane dies and her father later makes a mistake that leads to the plane crash, it feels like more than just a chain of events. To me, it's almost a metaphor for Walt's entire meth business.

Throughout the show, it's easy to rationalize Walt's actions because he rarely causes harm in a direct, obvious way. He isn't personally pulling the trigger every time, and he can always tell himself that he's not directly responsible for what happens afterward.

But the Jane/plane crash storyline forces us to confront indirect responsibility. Walt didn't crash the planes himself, yet his decision to let Jane die set off a chain of events that led to a huge tragedy.

What's interesting is that many viewers judge Walt harshly for Jane's death and the consequences that followed, while being much more willing to overlook the fact that he's manufacturing and distributing meth. The harm caused by meth is more distant and abstract, so it's easier to ignore, even though it also destroys lives through a long chain of consequences.

In both cases, Walt isn't committing an obviously evil act right in front of us that immediately turns us against him. The difference is that the show makes the consequences of Jane's death visible and personal, while the consequences of his drug empire mostly stay off-screen
