I'm all over the map on this one but the greater part of me shies away from giving anyone the legal right to kill. Yes yes yes, there are valid reasons for thinking about euthanasia--no one wants to suffer or watch their loved ones in pain. My mother suffered before she died and it nearly killed me to experience that.
But isn't life about suffering? Joy and happiness, yes, but much suffering as well. Where is the line drawn and who gets to draw it? Aren't we really talking about removing the taboos against suicide--making it an acceptable option for anyone, anytime? Is that a wise thing to do? I don't know but it makes me very uncomfortable that we might take such a step.
A good friend of mine was in mental agony for a long time. I found her in her bed with a self-inflicted gunshot wound to her temple. She ended her suffering, I suppose, but had she seen beforehand the violent obscenity she committed against herself she might have reconsidered.
Emotional reasons, I've learned the hard way, don't necessarily make a right action. I'm afraid of legalized killing in any form.
