Normative ethics is a huge subject including a couple dozen sub-categories. Additionally, I'm not certain any fully formed moral system can be completely prescriptive. Drug lords tend to act as government themselves, so I'd begin with Drug lords and Dictators a good guide line for all in government: '"Do not impose on others what you do not wish for yourself." (borrowed from Kant).
A “fully formed moral system” couldn’t be completely prescriptive. The nuance of ethical dilemma, conflict between individual rights and obligations, and justly competing interests make for a terrain ever shifting under foot. This is the territory.
