People, this isn't about emo things
Obviously this animator did his job, because many great works of art were very offensive to the people of the day. For example the nude paintings back in the 1700-1800's, those shocked the art world of that day and offended people, and so by the comments made on this his movie is a success.
Also the artist is probably depressed and doesn't want to live life anymore, and he wants to make his last moments something to be remembered and to live on through generations (metaphorically speaking).
