The section you quote is not really relevant to my broader point.
As for:
> The suicidal person is in no way accountable for others feelings.
I disagree very much, and the few things I have seen from people who are suicidal suggests they would disagree as well. Suicidal people really hate the effect they have on others. And just in general, people are accountable for how they make others feel.
As for the broader point. I do not think that "killing yourself will hurt others" plays a big role in cases where people should not kill themselves, but I do think it plays some role. And moreover, I think it is inconsistent to say we can't force people to suffer by staying alive if we can force other to suffer by ending our own life.
> It's akin to as if a debt collector could come after you for your deceased parents debts. In the U.S. at least, that's illegal, because it's obviously bullshit.
I don't see the analogy at all.
