Necessity is not a defence to murder.
>To preserve one's life is generally speaking a duty, but it may be the plainest and the highest duty to sacrifice it. War is full of instances in which it is a man's duty not to live, but to die. The duty, in case of shipwreck, of a captain to his crew, of the crew to the passengers, of soldiers to women and children, as in the noble case of the Birkenhead; these duties impose on men the moral necessity, not of the preservation, but of the sacrifice of their lives for others, from which in no country, least of all, it is to be hoped, in England, will men ever shrink, as indeed, they have not shrunk.
>It would be a very easy and cheap display of commonplace learning to quote from Greek and Latin authors, from Horace, from Juvenal, from Cicero, from Euripides, passage after passage, in which the duty of dying for others has been laid down in glowing and emphatic language as resulting from the principles of heathen ethics; it is enough in a Christian country to remind ourselves of the Great Example whom we profess to follow.
R v Dudley and Stephens, 1884.
You act as if death is something to be forestalled, avoided, and thwarted at every turn. Well, I've got bad news for you user. You're going to die, and whether it's today or in 40 years is such an infinitesimal difference in the grand scale of the universe that it hardly matters.
Death is not the enemy. It's part of life. The most important part of a life worth living, is a death worth dying for.
