Obviously, your comfort mattered more than that of so many of the other passengers.
Smoking used to serve people as a calming agent when flying, before all of the expensive drugs began to be used to achieve the same effect.
Society has rejected the presumption that 70% of the other passengers and I should suffer rather than the addicts. The smoker's rude behavior and arrogance is a major reason that they lost the smoking wars.
