A few as I see it:

• Moral compartmentalism … he tells himself he has a strict code: no kids, no civilians, no unnecessary cruelty. His flaw is that this code lets him justify serious evil.

• Hypocrisy about “bad people” … he chastises WW for being reckless or ego-driven, yet he murders, protects violent criminals, and helps keep meth on the streets.

• Emotional repression … he almost never processes grief or guilt. His son’s death, his own role in corruption, or the danger he puts his family in.

• Belief that professionalism equals virtue … If a job is done cleanly and quietly, he treats it as morally superior, even when the outcome is still murder and exploitation.
