Why Shakespeare wrote tragedies in his second period

I think the reason why Shakespeare's works are mostly tragedies also takes into account the tradition of Western literature. In the ancient Greek period, Aristotle had a systematic discussion of tragedy, that tragedy can purify the human soul, so that people have a sense of sublimity and pleasure. And Shakespeare's thought will inevitably continue the tradition of promoting tragedy in Western literature. Tragedy has more aesthetic value and vitality than comedy, and tragedy is more profound and causes more thinking. Moreover, from the point of view of the current situation of human existence, human beings live more in pain and misfortune, tragedy will inevitably appear, and the ultimate concern of human beings also makes people realize the need to reflect tragedy. Fate and circumstance bring a sense of tragedy that is difficult to decipher.
