Well the creators of the substance (manufacturers who used asbestos in their products) and the contractors that installed the products did in fact also get cancer. You're both a little bit wrong, and both want to be right, so seem to be ignoring the negative aspects of both your arguments. C does not have a direct proven link to causing death or catastrophic disease like asbestos does, but any bugs due to language "allowing" the dev to shoot themselves in the foot is largely born by the users - at least initially.
