The AMC series Breaking Bad had its last episode last night. Various people are writing various things about the various themes explored over the course of five seasons and about the character 'development' that went along.
Something that occurs to me is that the whole thing can be viewed as a study in incrementalism. The main character, Walter White, can be seen as a metaphor for the United States and their Vietnam policy in the 1960s. Both went in with good intentions. Both meant to get right back out, as soon as one simple objective was accomplished. Both experienced unintended consequences beginning pretty much immediately and persisting. Both, when faced with a rebuff, committed more resources to problem resolution and renewed pursuit of the objective.
Both ultimately failed. But not before horrifying themselves and witnesses with how low they could go. One day you're pledging to 'protect Democracy' in a far away land, the next day you're dropping napalm on children. And insisting that you're right to do it.
One step at a time.
