LOL, there is quite a difference to taking an aspirin or medication to help oneself feel better, and having a doctor help to kill a patient. I don't expect anyone to understand this, especially those who don't believe in an afterlife, so Im not getting into it with you, it would be pointless. Of course no one wants to see anyone suffer, and It is God that gives doctors and science it's sucess, another concept lost on those that don't beleive......Anyway from my perspective there is no dignity in unnatural death unless you are giving your life for someone else. How about instead of death with dignity, it's called pity killing.
Try for just a moment to look at it like this; Suppose someone did something/s really shitty in their life, and they are suffering for that later on in that life because God wants every one of us to get to heaven. So in that suffering they find God, they give their family courage, and when they do die, they get unimaginable happiness. When you kill them you may be taking away their last opportunity to get that?
That's all Im saying??
One last question? What if the day after you kill someone out of pity, they find a cure for what that person had and now, oh well too late! You would probably say that's too improbable huh?
