Morally unwholesome deeds knowing the consequences but without unwholesome intentions

As far as I understand (of course I may be wrong), every act done voluntarily is born from some specific kind of intentions, and according to the nature of that intention, the act can contribute to perpetuate dukkha or to its eradication. What happens when one acts without any amount of aversion nor passion, doing an action which in most cases is considered almost inseperable from evil intentions and almost objectively inmoral, let's say, consciously killing a child or raping somebody, while knowing the consequences? Can those acts actually be executed without any amount of evil intentions? Is that even possible? Thanks in advance for your time!
