Morality by another name is ethics. 

in some professional settings, this is not true.  ethics are codified, morality is not.

The psychological aspect of what is good or bad is tied to empathy.  You know that biting hurts, so you refrain from biting when you don't wish to inflict pain.  It might take socializing with others before you getting bitten teaches you that lesson, but you eventually do learn it.

One way to describe empathy is in the Bible.  When asked which of the 10 Commandments is the greatest, Jesus replies, "Here is all you need to know.  Do unto others as you would have them do unto you."

Going a bit off topic, but just wanted to point out a correction:

But when the Pharisees heard that he had silenced the Sadducees with his reply, they met together to question him again. One of them, an expert in religious law, tried to trap him with this question: “Teacher, which is the most important commandment in the law of Moses?”

Jesus replied, “‘You must love the LORD your God with all your heart, all your soul, and all your mind.’ This is the first and greatest commandment. A second is equally important: ‘Love your neighbor as yourself.’ The entire law and all the demands of the prophets are based on these two commandments.” (‭Matthew‬ ‭22‬:‭34-40‬ NLT)

Going a bit off topic, but just wanted to point out a correction:

I might have gotten the context confused, but this quote is the one I was referring to.

Matthew 7:12New Living Translation (NLT)
The Golden Rule

12 “Do to others whatever you would like them to do to you. This is the essence of all that is taught in the law and the prophets.

in some professional settings, this is not true.  ethics are codified, morality is not.

True integrity does not require rules.  A codified set of rules may be encapsulated as an ethics policy, but the intent of the policy is the same:  to hold it's members to a standard.

Codifying a set of rules and abiding by them does not make one ethical.  it merely draws a line that you are professionally obligated to not cross.

We were not discussing ethics as they relate to professional behavior, but ethics of human behavior in society.  The reasons for, and limits of, ethics policies is a completely different subject.

Morality is about right and wrong.  Ethics are also about right and wrong.  We might use the term "ethics" in different connotations than "morals". but they both still represent a set of rules to guide us.
