I think Romeo and Juliet are fools. In Act 5, Scene 3, lines 119-121 Romeo says "Here's to my love [drinks] O true apothecary! Thy drugs are quick. This with a kiss I die. [falls]". In these lines, Romeo kills himself with a poison because he thinks Juliet is dead. In line 171 of the same scene, Juliet stabs herself because Romeo is dead. They killed themselves because the other was presumed dead. They each threw away their whole life just because one person could no longer be in it. If people killed themselves every time their loved one died, the human race would be non-existent. There is so much more to live for than one person. Other things can make you happy, you can move on. Romeo and Juliet were foolish in that they chose death over living without a singular person. There are so many other people they could have met (if this was real life) and they could have found someone else they loved.
