After reading the novel “Do Androids Dream of Electric Sheep” by Philip K. Dick. I think that sometimes robot/machine are more moral and ethical than human beings. In the story where all the humans dream to have a real animal not just because they loves animal but to show their kindness and wealthiness. Robot sometimes have a cleaner mind than human beings, and for many times human do things for greedy reasons, so i disagree that robot are coldblooded.
