Are the designers of TCP/IP responsible for everyone whose death was assisted by the internet? Are Orville and Wilbur burning in Hell for all the people who were killed by things dropped from planes? And God help whichever unfortunate human invented the wheel. Sorry for my tone, but I find this perspective naive and annoyingly sanctimonious.
I'm making tools. People can use them for whatever. I hope no one murderers anyone (unless they have a really good reason) but I'm only responsible for making sure I don't murder anyone, and so far I'm doing okay.
