The problem with cigarettes is not just that they kill you a little bit sooner, but that they cause many years of life of reduced quality. There's a bunch of stuff like COPD or stroke that don't always kill smokers but do make their lives much less pleasant.

Non smokers often make smokers lives unpleasant. :)

The children of smokers need hospital treatment more often than the children of non-smokers.

Of course that selfish harmful-to-others behaviour is going to attract condemnation.

Not quite as bad as dealing with relatives dying with cancer way too soon in painful ways, and in some cases orphaning their children.
