I believe that this interpretation is correct. Everyone has their own reasoning of whether or not something is right or wrong. While Creon thought he was doing the right thing, Antigone thought otherwise and did what she believed was right for both her and her brother. Just like in today's world, everyone has their own opinions of what is morally right and wrong. While someone may think one thing is wrong, someone else might believe it to be right.

And does anyone know if part of the assignment is commenting on someone else's post?
