Absolutely not. You asked for a general definition.
Morality is system for homo sapiens to live with one another. If you believe that a universe where all sentient beings live under the worse suffering possible all of the time is not desirable to those beings, then it doesn't take much to come to the conclusions that a moral system is one where people must seek to minimize or eliminate pain and suffering as much as possible. The system of morality also must be double blind, as if you were to agree to slavery, you wouldn't know whether you're the slave or the slave master.
There's an objective system for doing that, and most of it is self-evident.
Stealing and murder cause pain and suffering.
It's up to us to figure it out.
What's your definition of morality?
I feel no need to redefine morality and am happy with established definitions, eg:
: beliefs about what is right behavior and what is wrong behavior
: the degree to which something is right and good : the moral goodness or badness of something
