I think people should be allowed to choose and do whatever they want. If it harms others, there should be punishment. If it harms themselves, so what? Some people are just flat out bat-sh** crazy and do irrational things. If you wanna help them, YOU help them. Don't drag others into the whole "have mercy or pity or sympathy".
If someone is in constant pain, or can't take care of themselves (basic human functions like wiping your butt and brushing your teeth) should be allowed to end their own lives.
But then you have those religious nuts that think god created you and owns you so you can't do anything to yourself god would disaprove of. They'll always have an irrational perspective of life and will try to control things that aren't in line with their religion. In my opinion, that's futile and childish.
This is America, we used to be free to do whatever we pleased, legal or not. If we got caught, we got in trouble and served our punishment. There used to be a very obvious bold line that divided crimes that didn't really harm anyone (the ones that were fun and required an abundance of stupidity or teenage adventurism) and crimes that endangered all society (murder, drug dealing, ----). Nowadays people can commit a crime just by saying something. It's absurd, too much political correctness and hyper-sensitivity to "feelings" that should be disregarded.
