This is my concern too. Rhino would consider you haven't stooped to their level, but I think there's a point you pass where grading things is simply justifying your behaviour - some will agree with the justification, others will not.
Going along with this, whilst there are no doubt some psychopaths completely beyond rehabilitation, I think the death penalty is sort of a bandaid solution to crime. Not particularly deterrent, doesn't address the underlying social issues - a big thing in the states, just a way of saying oh well that ones done.
I think the way the United States society works has created an underclass of desperate people, with very little hope of escaping that scenario (other than, of course, the army, which is kind of deliberate as well), and the society would be better as a whole if they adressed alot of these problems, rather than just focus on extremely harsh sentencing for a variety of crimes that don't warrent it, and only serve to exaserbate the problem.
People who are against voluntary euthanasia generally have the worst arguments I have heard on any subject. Impress me!
Euthanasia and abortion are similar in my mind - Not a fan, but no real problem with legality. Abortion though I basically don't think should be needed in this day of a multitude of birth control options available, at some point there has to be some personal responsibility.
But of course abortion should be legal, because the alternative is backyard jobs (horrible) and there is a reasonable amount of times it's pretty valid (rape, incest, health of the mother etc).
Euthanasia, wouldn't do it myself, but can understand it being available for people. End stage of some diseases are absolutely horrid.
