Long before I have questioned these:
- How do we define good or evil?
- What is it that it takes for the public/somebody to do something good, or something evil?
- In primitive society, there wasn’t any morals or ethics exist, so where does good come from? And where does evil?
In the time of searching, I have come across different views on this.
These concepts though do not completely answer the questions, but they give some sort of insights of how good has been good and how evil has been evil.
From philosophy perspective, how we define a man’s action/doing right/good or wrong/evil can go three separate paths, as in above: Consequentialism, Deontology and Virtue Ethics.
