Its entirely a matter of perception. Good and evil do not exist. Rudimentary, there is no good or evil on earth or the universe for that matter. Everything just is. It is a perception that frames reality. So good and evil is based on perception, therefore, The perception of evil is based on the one percieving it. If you percieve something as evil, then it is evil to YOU.
We can choose our own frame of reality or we can choose the follow the frame set by another in his/her perception of good/evil.
Having said that...
In Islamic Sharia Law, stoning to death a Women due to her infidelity is deemed as just and good. To me, in my frame of reality it is unjust and totally unnecessary.
Now is that due to the laws of my land (England, UK) which deem this punishment unjust and unnecessary or is it simpily due to MY own frame of reality which has been defined by my own beliefs/values or lack of for that matter?
