That makes it subjective and not objective. The difference is bias. Objectivity is devoid of bias. Subjectivity isn't. That's why different people will see it differently.

It's harder to be objective about evil when you are the one doing evil to another.everyone will differ in how they identify the objective good and the objective evil.
