is there any proof that AI capable of having a moral disposition will ever exist? Why does an AI need to be capable of moral reasoning to perform actions we'd consider evil? The concern is that computers will continue to do what they're programmed to do, not what we want them to do. We will continue to be as bad at getting those two things to line up as we've always been, but that will become dangerous when the computer is smarter than its programmers and capable of creatively tackling the task of doing something other than what we wanted it to do. Any AI programmed to maximize a quantity is particularly dangerous, because that quantity does not contain a score for accurately following human morality (how would you ever program such a score). If you're willing to believe that an AI will some day be smarter than an AI researcher (and assuming that's not possible applies a strange special-ness to humans), then an AI will be capable of writing AIs smarter than itself, and so forth up to whatever the limits of these things are. Even if that's not its programmed goal, you thought making something smarter than you would help with your actual goal, and it's smarter than you so it has to realize this too. And that's the bigger danger - at some unknown level of intelligence, AIs suddenly become vastly more intelligent than expected, but still proceed to do something other than what we wanted.
