请用大学生英语水平给下面作文评分，描述其优缺点，用中文回答：People misbehave, so do artists. That's of whom we called tainted artists', referring to those who made mistakes against the law of morality. People have great arguments about whether trained artists should be back on the stage. While some of them wish to come back to their popularity and career, we are against that they should come back.  
First of all, morality is the bottom line of a person. If a celebrity loses morality, he or she loses the foundation of being a person, and should not continue to appear in front of the public as a celebrity. For example, Wu Yifan was disliked by society because he did not pay attention to the moral bottom line and thus violated the criminal law. His work had been taken down. Therefore, the prohibition of the return of immoral celebrities can maintain morality and establish a good atmosphere for society.
Secondly, in the entertainment industry, banning the comeback of immoral celebrities can have a warning effect on the industry, so as to regulate them. Wei Ya was banned for tax evasion of 703 million CNY, and then took the initiative to make money to pay taxes. Thus, it can be seen that banning the comeback of immoral celebrities can warn them and indirectly improve the overall quality of the industry.
Finally, as for society, celebrities play a role in moral model and influence the social atmosphere. Zhang Zhehan visited Yasukuni Shrine and made a series of pro-Japanese acts. These behaviors led his fans to blindly follow the trend and take photos at Yasukuni Shrine one after another, which had a very negative impact on the social atmosphere. Therefore, banning the comeback of immoral celebrities can prevent the social atmosphere from being distorted.
Generally speaking, from the perspective of morality, industry and social atmosphere, the comeback of tainted celebrities does far more harm than good. In principle, we should stick to the line and ban tainted celebrities from coming back.
