Betrayal (by Xuewu Colorful)

The word “traitor” or “traitor” means “traitor” or “traitor” in general. And the “betrayal” I want to talk about today is just between people. Why should betrayers betray? What mentality determines this despicable behavior? The psychology and mood of the betrayed. Is it the primitive bad nature of human beings or the choice that people often have to make when they have to? What was the struggle before choosing to betray? Or take it for granted?
