Programmer Humor

I don't think it's exactly the same. Now if the hammer has a mind of its own and can loiter in an alley and can decide to kill a passerby or not based on its own judgement. e.g. the owner told the hammer to kill passerby wearing blue shirt, and the hammer does it but has 0.1% chance of killing people wearing yellow shirt due to computer vision quirks. Does the responsibility of killing people wearing yellow shirt fell partially to the blacksmith? Did the blacksmith can sleep soundly knowing people wearing yellow shirt might not need to die if his programming is a little bit more better, even though he never sold the hammer for the purpose of killing people in the first place (it's his customer that abuse it).
