While I would recommend against the train method, I wouldn't view those brave enough to take it as selfish. After all, we are forced to live or use a brutal method for others to clean up so I would place the fault at the people who forced them into that situation without a way out rather than the victim. I also wish assisted suicide was legal, but I know it won't be for a long time as emotions continue to drive peoples' actions. I hope you make the right decision for yourself.
