Live ant let die

I wonder why people take suicidal inclination to be a bad thing considering free will and the right to choose what one should do with one’s life is a basic right (at least on words). The world is overpopulated anyway and if someone wants to make more room for the rest of the living (and those yet to come) doesn’t that someone deserve to be left to do it?
I’m thinking a lot about dying again-the burden of life just doesn’t seem worth the efforts and certainly is not worth the misery it brings me. Further more and definitely more important, there is not even a touch of hope in me that could change, ever. Alas, I’m not free to leave in my own terms.
