This is always a tough subject, and of course shrouded in emotionalism.
When one speaks of "rights" one really has to sit back and actually look at what rights mean.
Rights are defined as the legal, social, or ethical principles of freedom or entitlement; that is, rights are the fundamental normative rules about what is allowed of people or owed to people, according to some legal system, social convention, or ethical theory.
Saying someone has the "right" to die can be tricky.
As a fully functional and healthy human being I have the ability to die at any moment of my choosing, as long as I have the guts to do it, so to talk about whether I have the right to die is kind of redundant, as I cannot face any consequences whatsoever for ending my own life.
A crippled, terminally ill person does not have the ability to die at any moment of their choosing, and so that's where the real ethical and moral implications come into play.
There are many views on this of course, from the "they absolutely have the right to have the plug pulled on them if they choose" to the "all life is sacred and we aren't allowed to play god".
I know if it was me, if I was vegetable, trapped inside my own body, being fed through a tube, bathed by strangers every day, I'd want the plug pulled on me faster then Mitt Romney position reversal. But one also has to consider the feelings of my family, which family member would have the heart to actually do it, and is it fair that I put them in that position?
On the other hand some people are not so righteous, and abuse may take place.
My answer is simple, suicide attempts should not be illegal, it's redundant and stupid and it doesn't solve anything. It's redundant for a healthy person, able person to have a "right" to die, as they can do so anytime, mentally allowing and when it comes to the terminally ill, where their suffering is so intense and there is no chance of recovery, it should be decided on a case by case basis which isn't perfect but I'd welcome anyone to go through that suffering with no end in sight and say they'd rather not die.
