Djentleman21 seems to have this down All the scenarios seem to say something different about suicide, or the reasons for it The chair is to just let go, get away The building is out of human curiosity about death, heaven, etc (concrete evidence, great pun) The bridge is to get noticed (ie make a splash) It mentions a lamb choosing the slaughter, so it's innocent people (commonly symbolized by a lamb) choosing to die As was said, the platform is just the frequency and irrelevancy of suicide, possibly playing off of the "making a splash" line And "c'est la vie" is a French expression meaning "That's life", or more simply put, "Shit happens" Its commenting on our perception of our own mortality and that of others
