Yes, of course the method of suicide is immaterial. However, the voluntary aspect of suicide isn't always so clear. The way we look at the world and each other presupposes that our brains are more or less working correctly. I once had to explain every line of complicated mathematical code because it was going into the controller of something very important for safety reasons. The C code was automatically generated from a higher level language, and it turned out in that process of conversion that there were a few sections of "dead code", code that could not be reached. Normally the code generator eliminates dead code, but sometimes it has to leave it in because it isn't smart enough to prove that it's dead code. It isn't sure that this code can't be reached, whereas through some logical cleverness or other, we can see that this is so. The dead code required some special documentation in the software safety certification process, in part because there's no way to write a test that tests what it does. They asked me what would happen if that code was actually executed. My only response was that if it executes, something very bad has already happened. Imagine, if you will, a brain that for whatever reason finds itself in a configuration that it never should have been in, never would have been in if it were healthy and unimpaired. Something bad has happened to it. Can we be sure of the choices we would make in that state? How can we know? I tend to agree that "suicide victim" is an oxymoron, but a person who commits suicide may well be a victim of something else, whatever created the state of mind that led to it.
