Morality is to do good and refrain from evil; to praise good and condemn evil; to seek out good and keep away from evil.

Ethics is to figure out what makes something good or evil: understanding what we can mean by those words; and what sorts of actions, motives, or dispositions fall under those categories, and why.

Justice is to build social systems that promote good and deter evil; including establishing the facts of what someone has done, and prescribing actions to be taken in response.

I think simply put:

Morality is an inherent classification of right and wrong behaviors, often the result of tradition, upbringing, and/or society.

Ethics is a moral system at which one may arrive through philosophy and rational thought.

Ethics tends to define right and wrong in terms of its impact on human well-being, and not just as a inherent sense of right and wrong. As such, it may arrive at conclusions that feel "morally wrong" but actually perpetuate a greater well-being. (One example being utilitarianism.) This is also its danger, as one may argue oneself into a behavior which is rationally ethical but inherently harmful (e.g. eugenics).

The power of ethics is that it can be used to derive moral guidelines for new circumstances, such as AI or global ecological considerations. Such considerations can be derived from morality, but they have a tendency to not truly appreciate new variables and instead attempt to reduce new systems to familiar circumstances, thus often missing nuance.

I'd argue that ultimately, a sound ethical system must be derived from rational ethical thought, gently guided by sound morality as a safeguard against dangerous fallacies.

Originally, ethics were supposed to be a field of philosophy dealing with right and wrong on an individual scale, like virtue ethics, and morals, on a social scale, see "social mores." Over time, that distinction disappeared, and in some cases got flipped—see, an "ethics committee." So don't sweat it, they're interchangeable, and everybody here is just talking about the connotations they've picked up in different contexts.

This is covered in the beginning of this ethics lecture series (at 1:50). Ethics is about expressing your personal values in how you exist in the world, whereas morality is about being in harmony with society.

Please watch this ethics professor, because I'm just a guy on the internet. The whole channel is worth a watch if you're interested in philosophy.

Morality is the evolutionary selection pressure that human societies place on themselves.

Ethics is an attempt to calculate the optimal response to an event, for some definition of "optimal".

It's kinda like the difference between natural language and formal language. One is not designed, not static, and often not self consistent, but consistency isn't the goal. The other is a rigorously defined system that is scrutinized for inconsistencies, because consistency is the goal.

I don't have anything to contribute, but I would like to recommend this video because it's awesome.

how would YOU solve a moral dilemma?

Legality is a code of behavior shared by society at large.

Ethicality is a code of behavior voluntarily adopted by disparate individuals as a condition of inclusion in a formally defined community.

Morality is an individually defined code of behavior. However, morality is often shared by people of similar cultural background: that common background tends to lead them to adopt the same moral code.

Morality one component of ethics but not the whole. Ethics is the process of figuring out what to do. The other components are aesthetics and practicality.

In a philosophical discussion ethics are a societal code while morals are specific to the individual. In the early 90s it was considered unethical for gay men to marry in the US, but I found that prohibition morally repugnant. There is often a difference between ethics and morals but individuals are probably happiest when those two align.

Ethics is right and wrong. Think stealing and lying.

Morals are anything to do with life. Taking or creating life is a moral issue. Think kill, murder, rape.

An issue is typically one or the other. eg It's morally ok to kill someone in self defense. You wouldn't say it's ethical to kill someone in self defense.
