I actually never thought of it that way. You could be right to some extent in that he is indeed a good "moral deflector", but the main point I was trying to make still stands, in that one bag of chips is not something that will significantly change your chances for cancer or whatever other disease could be associated with eating a lot of the stuff.

Same with cigarettes. Indeed they have been undoubtedly linked to cancer, but still, if I smoke only one it really won't make a difference. Same with spam, one email every few months, as has been my experience with gmail for the past several years for example, really does not annoy me more than a mosquito could. There's a difference between working on a bad product such as, let's say hand grenades or other stuff actually made to harm, and working on a product that is definitely bad but only if you actually let it be, i.e. abuse it.

My point is that the blame is not on who makes the product, as the product maker does not make said product with the intention to harm, even if they do know that if you cross a line it will be harmful. The blame is on the person that lets this product ruin its life. Just like any drug. If I hit a joint right now, I guarantee that it won't harm me. But if I let it run my life and I stop working because I want to smoke weed, then the blame's on me, not on whoever grows the weed or even the one who sells it to me. Precisely the reason as to why we usually put age restrictions on certain things, as we deem children to be not capable of drawing this line between use and abuse of things that could end up being very harmful. However as we grow up we believe that we are then capable of taking responsibility for your life choices. Including giving yourself cancer or diabetes by only drinking cola and eating chips.
