Many people watch Breaking Bad and see a man who turns to crime to pay his bills.
They see a chemistry teacher become a drug boss to save his family from debt. But a dark secret lies in the way Walter White acts after he kills someone. He does not just move on from the violence or hide the evidence.
Instead, he starts acting like his victims in small and strange ways. He adopts their quirks and weaves them into his own life. This habit proves that he is more than a criminal. He is a man who builds a new identity by stealing from the people he defeats and adopts the traits of the dead to create his persona of Heisenberg.

Breaking Bad: Exploring a crucial Walter White trait

Taking habits from his first victim
This happens for the first time in the first season of Breaking Bad. He kills a man named Krazy-8. Before the murder, Krazy-8 told him that he did not like crusts on his bread.
As soon as Krazy-8 is dead, the teacher starts cutting the crusts off his own sandwiches. He never did this at the start of the show. This is the first time we see him take a piece of someone else's life.
Learning from Gus Fring and Mike
The pattern continues as the story of Breaking Bad intensifies. Gus Fring was a very particular man. He once put a towel on the floor before he knelt to be sick. After Gus dies, the main character does the same thing. He puts a towel down to keep his clothes clean while he is ill. He is acting just like the man he killed.
He also does this with Mike Ehrmantraut. Mike always drank his whiskey plain with no ice. After Mike is gone, Walter White starts to drink his whiskey the same way. He even begins to talk like Mike. He uses the same cold words and mean tone. He is slowly building a new personality out of the men he has murdered.
The writers of Breaking Bad put these details in the show for a reason. They wanted to show that the main character was losing himself. By the end of the series, he folds his napkins in a fancy way just like Gus Fring used to do. He is no longer the man he was at the start. He is a mix of all the men he has killed.

This makes the show very interesting to rewatch. You can see the exact moment he picks up a new habit from a dead enemy. Fans of the show can now look for these small signs in every episode. It changes how you see his journey from a good man to a monster.
