When *YOU* take an action *YOU* better be ready for the reaction. Anything less makes you a victim only to yourself.
It is very well documented that the reaction people were told they would have, which was a good one, by those who should have (and did) know otherwise, is not the reaction they actually got, which was deadly.
So while I agree absolutely that we are responsible for the outcomes of choices we make for which we understand the eventual and potential outcome(s), I deny just as absolutely that we are responsible for the outcomes of choices we make when we have been deceived.
I would have no problem whatsoever voting to convict a tobacco company executive of the previous century of premeditated manslaughter by poisoning. However, at this point, we know, or we should know, how utterly stupid smoking tobacco is in the context of our health, and yes, any individual capable of informed consent who is still (or begins) smoking today can't reasonably blame that on anyone other than themselves. And as long as they don't, and don't make non-consenting persons and animals inhale the carcinogenic pollution that results, I'm all for them smoking all they want.
