Through the media and the internet, we can often see the righteous acts of college students, but the outcome is often pessimistic. This just past New Year's Eve (February 15), another tragedy happened. Yang, a returning college student, was burned in a large area during the fire fighting and eventually died after being rescued. ? Such a tragedy has happened many times, and every time we feel sorry for such a vivid life. If he had not been so selfless and devoted at that time, perhaps such a tragedy would not have happened and a life would not have passed away in vain. In fact, sometimes selfish or selfless, I really can't think so much when I encounter difficulties, and I can't distinguish it clearly. If Yang chooses to retreat, will he be condemned by his conscience or the responsibility of society and public opinion? Our society often pays lip service to moral selflessness and is often vulnerable to moral kidnapping. In fact, selfishness is human nature and selflessness is morality. Society should not kill humanity, nor should it kill morality. Human nature is the truth of individual existence, and morality is the foundation of society. There is no individual divorced from society, and there is no society that does not depend on individuals. If everyone only cares about selfishness, what will this society become? I can't imagine, so as far as society is concerned, we can't encourage everyone to be selfish. We should devote more to society, to the collective and to unity. But we can't completely deny or even obliterate selfishness. From the perspective of social development, in fact, social development is nothing but selfishness. If we don't improve our life, many things will not be invented, such as "fire". We encourage selflessness, but we should also moderately support selfishness. Perhaps Yang could have been more "selfish" at that time, and such a tragedy could have been avoided.
