Your father also made the remarkable individual that you are. Humans are peculiar creatures and enjoy their petty habits and vices, even if dangerous. I know smokers. Talking sense into them is difficult.
Some of old geezers came from a time when smoking was looked at differently. Every other commercial was a cigarette commercial the others were for beer, whiskey or wine. Every box of C-RATS had a four pack of cigarette’s and a small pack of matches. The first cigarette I ever smoked was provided to me by the US Government in 1969.
