No one is accusing anyone of being a shitty person for considering the train method--ostensibly anyone considering this method is quite desparate and not motivated by a desire to harm others. That does not mean it is inappropriate to point out the morally questionable aspects of this method, in addition to its practical shortcomings.
There is a lot of consideration here of choice, appropriately so. Directly involving others in the act of taking one's life, without giving those others any choice in the matter, violates the principle of choice at a very basic level.
When people couch their arguments against it in terms like "anyone with a moral compass (would not do it)", as we've seen in this thread, this is unambiguously condemnatory language, as is describing it as a "very shitty method" on the same lines, the implication being that it's fine to assess the suicidal individual as someone of questionable moral and ethical standards. My own view is that when someone begins a thread saying "I'm considering the train method" it's quite jarring to see regular responses about the driver when, as we should probably understand on here, people who do this are desperate enough to prioritise the possibility of an instant exit above all else. I dare say they are probably unbothered by the prospect of making people late for work too.
The OP stated they have no alternative means of a quick ctb and when people on here state that they are considering this unpleasant but effective method l don't think it's correct for users of this forum to make them feel as if they are lesser people for doing so, if we're going to start guilt-tripping or character-assessing users for not choosing our own preferred method we're not much use imo.
Literally no one said OP is shitty. To remind someone how their actions effect another living being isn't a bad thing either. I never condemned OP for their choice. You compared train drivers as a protected class because I think it is wrong to scar them. As a whole I think we should desire to not traumatize people through our actions. Train conductor or not. I wouldn't think less of anyone who did the train route if it negatively impacted the mental health of the person driving our train . But we have to be accountable for our actions as people. I myself as an individual could never forgive myself knowing I possibly horrified someone and drove them to the same points as me.
This last sentence in particular kind of evidences the point. You yourself as an individual could never... well so what? I personally could never hang myself knowing it could be a loved one who stumbled across my swinging corpse, but it's an effective method and people get desperate enough to consider it, if their need to ctb outweighs this aspect for them then it's not for me to condemn.
The point is who are we to judge on this basis, and every time someone pops up in a thread from someone considering this effective method to talk it down in accordance with their own ethical standards is, by implication, passing shade over the person considering it.
