Morality without the righteous. What is right and wrong?

[Muslim Scholar]

"It is wrong to cause harm to others."
What does wrong mean?

"It is right to be helpful to others."

What does right mean?

Right and Wrong cannot be absolute, they are only defined relatively
If you believe in God, then he defines what is wrong or good
If not, then it is usually what the majority (or in power) accept as wrong or good

for example it is right (for most people to eat chicken) but I'm sure it is wrong (from the chicken point of view)
