  In the absence of any definitive arguments for or against the possibility of future computer systems being morally responsible, researchers within the field of machine ethics aim to further develop the discussion by focusing instead on creating computer system that can behave as if they are moral agents (Moor 2006). Research within this field has been concerned with the design and development of computer systems that can independently determine what the right thing to do would be in a given situation. According to Allen and Wallach, such autonomous moral agents (AMAs) would have to be capable of reasoning about the moral and social significance of their behavior and use their assessment of the effects their behavior has on sentient beings to make appropriate choices (2012; see also Wallach and Allen 2009 and Allen et al. 2000). Such abilities are needed, they argue, because computers are becoming more and more complex and capable of operating without direct human control in different contexts and environments. Progressively autonomous technologies already in development, such as military robots, driverless cars or trains and service robots in the home and for healthcare, will be involved in moral situations that directly affect the safety and well-being of humans. An autonomous bomb disposal robot might in the future be faced with the decision which bomb it should defuse first, in order to minimize casualties. Similarly, a moral decision that a driverless car might have to make is whether to break for a crossing dog or avoid the risk of causing injury to the driver behind him. Such decisions require judgment. Currently operators make such moral decisions, or the decision is already inscribed in the design of the computer system. Machine ethics, Wallach and Allen argue, goes one step beyond making engineers aware of the values they build into the design of their products, as it seeks to build ethical decision-making into the machines.
