So if a 12 is getting bullied non stop, and commits suicide it would be okay? just because someone is in pain doesn't mean they have the right to end there own life. Suicide is illegal, like euthanasia.
Also on the part about pain growing someone up was obviously not ment for someone who has already lived a long life, for they are already grown up. Please do not take things out of context. :D
You don't appear to know what you're even talking about. Regular suicide, non-consensual 'mercy' killing, and euthanasia are all different things.
Suicide, which is what you're describing, is a completely different subject and the fact that you're attempting to use that as an example makes you look completely foolish. That's
emotional pain, not physical pain.
I associate the term "mercy killing" more as killing a person who is injured and likely to die anyways... like, say you're trapped in a desert with someone, with no food, water or medical supplies, and they break their legs and are in horrible pain, with no way to get help or move. Lets say you have a gun. They decide that a bullet to the head is probably better than staying there, starving and dehydrating, waiting for the wolves to come and eat them. They ask you to do it for them. That would be more "mercy killing" to me. More of an emergency thing.
Euthanasia would be more like cancer patients with no hope of recovery, or old people who are dying of old-person problems. I think it should be allowed. It's their life, and it's absolutely none of your business whether they live or die if that's the choice they make, especially when it's more a choice of "live for a few more horrible hours/days/months, then die" or "die now relatively painlessly".
People who are on life support and can't make a decision are more of a gray area. If they decided beforehand, then of course their decision should be respected. If it's up to the family, then they should decide whether there's really a good chance of them ever recovering.
tl;dr - It's no one's business but their own and they shouldn't be forced to suffer because of the beliefs of others.
