When these children grow up, becoming fathers or mothers, sometimes, they will mimic the actions of their parents subconsciously, and then affect their children. The vicious circle will continue and continue, which definitely damage the human social civilization.
Besides, people consider infidelity as the most unpardonable thing because it disobeys the morality of human society. Marriage includes not only love, but also responsibility, trust and courage. In fact, although many people in Europe or America have a lot of lovers before their marriage, when they decide to marry somebody, they have already prepared to undertake the responsibility. It is believed that every couple remember the swear on their wedding:"will you love him (her) even though he (she) is ill, poor, painful or dying?""Yes, I do." Therefore, a married person should not forget this and find excuse to indulge his (her) desire.
However, other people insist that everyone, including the married people, has the right to find true love. They emphasize that a person can live in the world only for several decades. Why does the society limit their right to seek for the true love? In the real life, so many tragedies of families occur because of couple's different personalities, living habits and minds, which would cause a long distance of hearts. If there is no fun, no passion between couples, how can the society rebuke them only due to a marriage certificate?.
Another common objection is that it is really hard for people to control their feelings when they fall in love. Some married guys who have emotional affairs with others outside marriage are not the people who have little emotion with their families, but the people who have the feelings like self-reproach, pain and sufferings. However they still cannot help loving others. After a long insipid marriage, certain people outside the marriage have attracted their attentions, and then their desires of love have been rekindled.
