It is absolutely nonsensical to think that someone who creates a thing should be held responsible for every negative use or misuse of what they create. It's even more nonsensical to expect someone to come up with every single one of these scenarios that could possibly happen. It's just not realistic, doable or even helpful. At best, it will have an extensively negative effect as every single new development will be tut-tutted into the shadows by a group of hand-wringers, terrified of a user 7 sigmas away from the mean might do with it one day. This is an appalling way to construct a society, let alone a discipline that requires rapid, ground-breaking iteration.
