Science can actually answer many questions in the realm of morality and that science is called psychology, also with the help of Neuroscience. In the same way for example that psychologist can determine if a person has psychopathic tendencies which is mostly about the lack of empathy; in many cases This specific part of your brain is called the the right supra-marginal gyrus. When this brain region doesn't function properly—or when we have to make particularly quick decisions—the researchers found one’s ability for empathy is dramatically reduced. This area of the brain helps us to distinguish our own emotional state from that of other people and is responsible for empathy and compassion.
But if we're gonna take logic with no science references I think when it comes to morality science is the closest thing that can explain or interpret our moral compass because science is about evidence and proof and studying multiple cases before coming to any conclusions which is more co-existence with morality than any other method created by mankind.
Many people claim that Religion is a better answer for human's morality, as much as I would like to agree with this point because it would be much easier to determine which acts are moral and which are immoral by just reading it from a book but I can't really Agree for the reason that different religions has different books which makes them have different moral reasons for certain acts. which makes the morality dependable on what the person has been taught from a young age, or what societies claims moral reasoning for certain immoral acts, like Honor killings for example is a very big issue where I come from and the Killer can go without an equivalent punishment for the homicide he committed just because culturally it is in some way acceptable to kill your sister or wife if you caught her in the act of having sex with another man. and that's not just in a court of law, its also acceptable in society which sometimes even praise this act and make parents or relatives of the killer even proud of his doing.
