Why are Cancer boys so vindictive and vengeful?

Because I am too kind and emotional, I have thought that others are as kind and emotional as myself since I was a child. When I was betrayed and hurt by calculation, Cancer began to know the world again, only to know that not all people are as kind and emotional as themselves. Cancer is very clever. There are also tricks and routines. Cancer can see that it is not as stupid as fire. Cancer will start to hate each other when they see what they think. Because my sincerity got the calculation of others, I began to want to retaliate against those who betrayed themselves and calculated to hurt themselves. This kind of revenge can not be ended once or twice, and it must be retaliated until the resentment and hatred in his heart are eliminated. If the hatred is not eliminated all my life, I will use the rest of my life to get back at you. Time, place, form and frequency are not fixed. I will secretly retaliate against you anytime and anywhere. Some people will say why Cancer is such a villain. I am embarrassed that Cancer is naturally a sincere friend to a gentleman.
