Actually, there is - LOL Just realize this:

Hamlet is often perceived as a philosophical character, expounding ideas that are now described as relativist, existentialist, and sceptical. For example, he expresses a subjectivistic idea when he says to Rosencrantz: "there is nothing either good or bad, but thinking makes it so".

Which means that you, uncreativeartist, are not wrong in questioning why society doesn't discuss this subject. You think it's right to discuss it, others don't. People perceive things differently and therefore express those differences.

The idea that nothing is real except in the mind of the individual finds its roots in the Greek Sophists, who argued that since nothing can be perceived except through the senses—and since all individuals sense, and therefore perceive, things differently—there is no absolute truth, only relative truth.

Same as above - people perceive things differently. Hamlet discussed suicide and decided that people live and think about suicide because life is truly hard and people are cruel; however, because people also have different ideas of what it means to die, and many are frightened of what that would mean to them, based on what they know of life and death, they don't take that final step and commit the act. Therefore, fear of the unknown makes people continue to suffer the known which is a continuation of how life will remain really hard and people will remain cruel.

The clearest alleged instance of existentialism is in the "to be, or not to be" speech, where Hamlet is thought by some to use "being" to allude to life and action, and "not being" to death and inaction.

Again, personal perceived fear of the unknown stops people from taking the final step, although they continually think of it.
