Maybe having a 17-year old child yourself is the clearest way of
answering this question

I'm sure his parent's will be distraught, quite understandably, and will
tell the rest of the world that he was a good boy, equally understandably.

However, the fact remains that a 17 year old has sufficient knowledge to
know that if a human body puts itself in the path of a train travelling at
100mph there is only one outcome. Why have compassion for someone so
reckless with his own well being? Try answering the question, if only for
those who don't have 17 year old children.
