> So does morality/ethics boil down to numbers/metrics?

The field of ethics essentially considers how to build and analyse arguments. Ethics generally does not make decisions; and it's not a flowchart you can follow to get a yes/no answer, either. People often use the world "unethical" as-if it is a proper adjective, meanwhile it actually refers to themselves having concluded that the act/object is not ethical within their reasoning; it's not an actual property of an act or object.

Much like broad philosophy, it's a language for expressing thoughts. It doesn't think for you. Or, if you like, mathematics is a language for expressing some other thoughts. Mathematics doesn't solve problems for you, or prevents you from writing 3+1=5.
