I see you still don't understand it.
Let me do this one last time:
1. "2 wrongs don't make a right" is a set phrase in English. It's an expression. One doesn't normally change an expression because it's idiomatic. You may not have grasped that in your English class, but it is what it is.
2. General terms can and do represent a variety of concepts. "Right" and "wrong" can be general terms, and they are in that context.
Let me give you an example: "developed" countries.
For a country to be "developed", it's not just one thing or two. Just to name a few, they'd have to have a certain amount of wealth (the concept of wealth), distributed relatively equally (the concept of equality), have a low enough crime rate (the concepts of safety and security), have good enough infrastructure (the concepts of material development, transportation/accessibility etc), have adequate public service (the concepts of public education, education, public healthcare etc), and so on.
Whilst the overall outcome could be summed up by saying it is or is not developed, there are clearly many concepts involved and many calculations before reaching such a conclusion.
3. As I've said, different things can be subjected to different sets of standards. With massacre, I used the moral standpoint; with imperialism, I saw it from the standpoints of justice, human/civil rights, diplomatic relations, economic development, culture etc. It may be difficult for you to understand this, but it's true.
I really thought the shopping analogy would have been sufficient, but I guess it's true that intelligence cannot be taught, and your limited brain power is just inadequate to process ideas that are not simple enough for a kindergartener to understand.
