It's a wicked and/or a pathetic thing to commit suicide "freelance" --- only God can judge in the case of the clinically depressed or otherwise impaired. But that doesn't even compare to the rotten evil of "legal" or "assisted" suicide where you corrupt the major institutions of society as your accomplices.
Doctors, nurses, and hospice workers should not be pulled into the picture as accessories to the deed, because they are, and shoule be, unalterably committed to the patient's health: and nobody is healthier dead. Lawyers, judges, and politicians should not be implicated in suicide because they're supposed to be dedicated to our rights and liberties, and death effectively snuffs ALL rights and all liberties.
I have never quite understood why those would-be suicides who say their #1 value is personal autonomy, don't just do it --- like those other 30,000 self-respectng autonomous suicides* --- and leave the rest of us out of it.
* (Hoping the irony here is apparent.)
Another thing the culture of death has tried to do is change the meaning of the word dignity. Dignity comes from character and there are plenty of people who APPEAR very dignified, yet have no dignity. And yet most people do not appear dignified at the time of their death, but they can still have dignity. When our Lord was on the Cross, His appearance was probably anything but dignified, yet He possessed more dignity than any of us will ever appreciate.
Almost all of us at some point (and for most of us it will be several times) experience watching a loved one die. And of course we would do anything to relieve their suffering, but that is not an excuse to kill.
