Me? Yes, those who go on a programmer-killing spree are unlikely to be viewed favourably by me. I don't think all murder is impossible to justify - but prospective killers would need to be really, really convincing about their motivation in order to avoid being black-balled by the rest of society.

"I have this paranoid fantasy about their mechanical offspring taking over the world" - is the type of thing that would not normally be regarded as adequate justification for killing people.
