If I set up a tripwired explosive that kills someone, I would be rightly judged a murderer.

Nope. Not if 1) the person asked you to do it, and 2) you told the person where it was, so they could avoid it if they chose to.

Sophistry. Suicide is, by definition, the killing of one's self. It is not the intentional enabling of or commission of a killing by someone else. The name for that is homicide.

You may wish to reclassify the homicide of willing victims to the class of legal and/or justifiable homicide, but don't fool yourself into thinking it isn't killing another person. And don't think you can disguise what it is with sophist phrases like "mercy-killing", "death with dignity", "coup-de-grace" or any other obfuscation. It's that sort of self delusion that has lead to millions of unjustified abortions every year.
