I think you have a BIG misunderstanding about what Euthanasia is.
You though Brendan have a deeper misunderstanding what self defense is.
You go and ask any lawyer:
You have disarmed your assailant,
you have him bound securely on the floor.
You consider that should he be released, the he will seek you out and kill you.
So you kill him now.
Any lawyer will tell you that you would be guilty of murder.
Self defense can
ONLY claimed in case of heat-of-the-moment. When blood is hot, and life is in immediate danger.
Self Defense is not euthanaisa,
As I said, this is not self defense, as the immediateness is no longer the essence.
do you really think that the State executed McVeigh because he was suffering too much?
Is a rabid dog euthanased because it is suffering, well yes, but also the consideration is that it is lethally extremely dangerous.
Cattle with foot-and-mouth-disease are not suffering a painful and incureable disease, the disease is quite mild, and it is quite cureable. Further, innoculation is effective in giving immunity.
No, the cattle are euthanased because it is ecconomically preferable to have a certified disease free stock, which recovered and imune animals make impossible to certify.
Thus euthanasia is not necessarily used to relieve suffering, but as a defense against an ecconomic threat.
Euthanasia, according to your own definition, means only an easy death. There is no implication for its reason. Mercy is irrelevant. It is just a humane killing. This is what the majority of means of execution today try to achieve.
McVeigh was neither hopelessly sick or injured, and the State didn’t execute him out of reasons of mercy. there was no euthanasia involved.
Euthanasia has nothing to do with mercy, it means only:‘easy death’.
Neither was there vengance. Only a desire by the State to prevent him from doing more damage to Society.
So the state euthanases a dangerous individual to remove the danger threatened thereby.
If done without un-necessary torment of the victim, fine, but still euthanasia.
If though, the victim is tormented then evil is being repaid with evil, and the retribution is vengeance.
But since I (and the Church) see it as a form of Self Defense, there is no sin.
Mother Church accepts this definition if, and only if, there exists no practical alternative.
At the time it was put into the catecism, that was the case. now it is not, at least in civilised countries it is not.
Perhaps then countries employing Capital Punishment are not civilised?
You then be the judge.
