Conversely, I fail to see how anyone who is so opposed to the death penalty that they would consider it akin to murder would support euthanasia, Life is life. Both capital punishment and euthanasia are based upon the proposition that life is not so precious that it should never be ended.
Perhaps, but
opposition to capital punishment does not have to rely on the reverse of that proposition.
Needless to say, I do feel very strongly that judicial murder is always an unethical act regardless of what crime has been committed, and a disgusting burden on the relatives of the condemned, only compounding the suffering in a barbaric act of bestowing revenge upon people who have not done anything wrong. It is not the role of the state to execute people.
What any of this has to do with a private, consensual medical decision is lost on me.
