C
Several months ago, CCTV broadcast a documentary(记录片)film about criminals(罪犯). I remembered one criminal clearly: he had killed his girlfriend just because she wanted to leave him. The journalist asked him, “Do you regret killing your girlfriend？”
“No.”
“Why？”
“It's useless to regret，”the man answered calmly.
The journalist was silent. At that moment, I felt very angry. This man had made such an unforgivable mistake but he still wouldn't say he was sorry.
Is regret really useless?
Of course, regret is an emotion linked to the past and this feeling cannot turn back the clock. But I think people who say regret is useless ignore(忽视)two points. One is that regret is useful for the future and to one's soul. Look up the word“regret”in a dictionary: there are many expressions, such as“repent(悔悟)”，“chagrin(悔恨)”and so on. All these are used to tell people not to make similar mistakes after they have realized their fault. If you don't regret, how can you repent? On the other hand, for those such as murderers, who have already lost their future, regret is still a baptism(洗礼)for the soul. A murderer won't leave the world at peace with himself unless he understands what regret is.
I have no doubt that regret is a virtue. Just like a light in the darkness, it can offer people the ray of hope they need. No matter what you have done wrong, people will always respect you for showing regret and a willingness to correct your mistakes. In this way, regret is a special feeling. Correcting mistakes is better than complaining; it makes you feel good about yourself. So why not show some regret after doing something wrong?
