This chap has thrown in the towel on himself. It's not a question of pushing where it's not wanted, it's about giving someone the opportunity to grab on to what might be the last threads of his life and to make choices.
Sometimes, just sometimes, you need to hear that other people - and that includes strangers - care about you.
When I was in the police, I had to break in to a house out of concern for a man. He had nearly succeeded in taking his own life. When I popped into the hospital a few days later he told me I was the only person who hadn't given up on him. When I listed all the people who had a hand in saving his life (concerned neighbour, police operator, my colleague, the passerby who helped break down the door, the paramedic, technician, a and e staff, porters.... The list goes on), he simply said 'I am worthy of living but never knew'.
As someone said before even if he picks it up and reads it then it's worth it - whatever the outcome.
