Well, I do agree that the human race has failed millions of times and that sometimes life does seem very pointless as we continue to destroy the Earth. You seem like you suffer from low self-esteem judging by all the "flaws" you say you have. So it's come to this. You want to end your life. You don't see the value in goal achievement and that's fine because in the long run, your physical life is pretty short. With comparison to the infinity of the universe, your life is nothing more than a blink of the eye. But you can still have a good time on the Earth and enjoy yourself. You don't have to spend all your time contemplating suicide. Do what you love to do, stop thinking about ending your life.
