@Gothix I know i'm quite late and the party is long overdue, there's no more rum, and the hookers are exhausted... I'm still going to drop this. Even though acceptable behavior is indeed subjected to cultural (more likely survival compromises dictated by ecosystem that have become traditions and stuck even though the reasons behind them are overdue) dominance, there still exist what the ancient Romans defined as "natural rights". They recognized such rights to slaves and animals and even objects. It basically refers to not deliberately hurt another without proper cause. Yes the Romans where businessman and profit was proper cause. But they where acknowledging it as an evil act. Also, selflessly helping another will always be an act of good. Therefore. Good and Evil can be universally defined. What confuses people is the judicial recognition of an act as acceptable or unacceptable in a certain law system. That is indeed subjective to context. In the same country, under the same administration, death sentence is forbidden during peacetime and common during wartime! Still it will always be recognized as a necessary evil!
