I really thought about this and something that I came up as black and white could be maths?
1 + 1 will always = 2 unless theres something else I'm not seeing haha
Hmm. I don't think that's a good analogy.
I'm sure you can think of even mundane cases where "wrong" things can be right under certain circumstances (Killing another human being is wrong, but what about in the defense of your own life?).
And there are many things that depend entirely on social custom and vary greatly between cultures or timeframes (there are periods in history where pedophiliac homosexual relations with young boys was normal and even expected--something we'd all agree is repulsive nowadays).
And there are even
degrees of rightness. You can do The Right Thing, but what if you did
more of The Right Thing? I can donate $10 to charity, or I can donate $20 (a simplistic example, I know).
Right and Wrong is an entirely man-made concept and is specific to everyone and is directed by context. I think it's impossible to say with certainty anything is right or wrong. We as a society agree on certain things (laws, social taboos etc), but there's always shades of gray we all consider.
