i dont understand how people can say that they cant understand why walt is the way he is now. to me it makes perfect sense seeing that:
1) he watched his father die from a debilitating disease at a very young age
2) he was emasculated by skylar for the better part of their marriage and the show
3) his greatest creation, grey matter, was stolen from him
to me these three factors create heisenberg:
a) his fear of death and being not able to provide stem from his father.
b) his ruthless, cajones of steel alpha male mentality from being repressed under skylar
c) the absurd amount of money gretchen and eliot made off of his intellect and genius
his motivations are to correct the things in his life that were changing.
first it was seeing the money on tv at his party.
then it was seeing his fantasy woman at the carwash before he passed out.
then it was his life, getting the cancer diagnosis.
