While I do applaud the efforts of the people that ended up saving this guys life (and it was quite an extraordinary event), I do somewhat agree with what Ravr was trying to say... Although I don't think he did a particuarly good job of presenting his side of the argument.
On one side, it is seen by many people as a moral obligation to try to intervene when someone makes an attempt at suicide. People feel the need to save someone from their own choice of death over life, because perhaps they feel that said person is making the wrong choice.
While it may be the wrong choice in one persons eyes, it is quite simply the choice that the person decides to make. What if they truly do want to no longer live? What makes us think that it is ok to prevent such a person from making a choice like that? After all, the right to live is the right of that person to live. They can choose to live or not to live. Who are we to step in?
That being said, if it was me in that position in that I felt there was no other way out but to take my own life, I don't think I would want someone to intervene on my behalf because they think they know what is better for me.
On the flipside however, I don't think I could hold myself back from trying to save another person if I were in a similar situation. It is human instinct and moral obligation to try to intervene when faced with such a situation.
