That is merely wishful thinking and total disregard for the other party’s suffering. To keep someone alive when the continued existence only brings forth more pain, more suffering and loss of dignity (there is no “dignity” in being devoured by rats while being still alive and conscious) is an incredibly cruel and heartless torture. That is “Room one-oh-one” in the Miniluv (Ministry of Love) in 1984.
Your understanding is limited by your worldview, enduring terrible suffering now can lead to glory in the hereafter. The martyrs of the Church all suffered greatly in their dying, but for enduring that suffering the reside now in heaven.
For the vast majority of those people, who are not martyrs, like you and I suffering can lead to greater understanding of one self, of others, and of God.
I’m sure you know Matthew 19:24 “And again I say to you: It is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of heaven.” Badly paraphrasing Gregory the Great here, the statement is much less about rich versus poor, and much more about those who suffer and those who don’t (or worse) cause the suffering of others. The camel (that which is ridden, a beast of burden, often hungry and thirsty) represents those who suffer, the rich man (the one who rides, whips his beasts, and always has food or drink) those who do not. Christ is telling us that suffering in our life has a purpose, without suffering, it is very, difficult to enter into heaven.
Compassion means compassion. Coming from the golden rule and putting ourselves into the shoes of the other party. In similar circumstances I would prefer to be killed, fast and relatively painlessly. And if I would be in the position to express that wish, I would ask for that quick release. To deny such a request is tantamount to cruel torture.
It doesn’t matter what you would prefer, thou shalt not kill others (including the unborn) or yourself, we are not allowed to choose when we come into this world or when we leave it.
Rau said that “we are never compelled to sin”, but that is just empty utterance. It reminds me of the other empty phrase, which says that “God always gives sufficient grace so we can endure whatever hardship he happens to pile upon us”. The people who commit suicide obviously did NOT get that “sufficient grace” (whatever that might be).
To say that we “put ourselves in front of others” is simply an insult.
It’s a straight fact: you are never compelled to sin. I am never compelled to sin. There is no situation that will ever occur to anyone, anywhere throughout the universe, where the answer to WWJD is commit a sin. You can write a million hypotheticals and there is always a morally correct exit. And as for Evil: Satan and his ilk, contrary to Hollywood, they can’t compel you to sin either. He can only whisper in your ear: a small voice telling you to do what you want and damn the rest. It is your choice to listen to him. Now in some cases the morally correct exit results in your death (Gunmen holds a gun to your head, gives you a gun and says kill this person, or I kill you. The morally correct response is to let him kill you) which is to say the morally correct choice may be very difficult, thus, yes, when you say compassion, you mean convenience.
And as for suicide, people commit suicide because of a lack of hope caused by their loss (or absence) of faith in God, egged on by a society that glorifies death through abortion and euthanasia. Christ is hope, reject Christ and you are left with Abaddon…
