Yes.... I know this is my killer machines month, but..... I just have to add GLaDOS in as a killer machine..... Why? Well because she killed her creators that's why.... She's a perfect example of a machine becoming to smart for our own good, and she tries to justify it by saying that it was all for the benefit of science and mankind... When really she was just being insane..... And that's what puts GLaDOS on my list of killer machines....
