I am sorry, that I simply do not understand how anyone can use the word 'selfish' to describe an event that has bought so much personal pain and emotional trauma to a conclusion. Yes, this so-called 'one under' like all suicide methods, has a massive effect on so many people. Indeed, suicide always has huge effects on so many, family, friends., colleagues and so on - plus those who are called in to clear up the emotional & physical mess left by such a dramatic event such as being struck by a 120 MPH train.
I have been one of those involved in the clear up, (and rescue of those who are terribly injured but survived) of many suicides including those who jump from tall buildings, set themselves alight and dive under trains, and trust me, it ain't nice. But my thoughts were always with those who had been in so much pain to have gone through with this act in the first place. I have experienced emotional ups & downs - perhaps we all do, but I cannot imaging being so low to kill myself.
If I ever find myself on that path, I may also choose the Network Rail train route, as other methods of suicide are far less reliable. Is that selfish or sensible when your aim is to die and not end up severely crippled thereby worsening your pain?
BTW, I understand that this victim was a 19/20 year old ex pupil of Douay Martyrs School (and was known by my daughter). It's so sad that such a young man has died in such circumstances, but evidence that one of the biggest groups of suicide victims are young men
