Help to recover a person willing to suicide?
Lets put a situation:
You are walking on a road bridge and suddenly watch a man/woman standing at the edge of the bridge, and you know he/she is going to jump soon or later.
Now, watching it from afar. Do you, as human being, in a sensible way, think that have some sort of responsibility in terms of the widely universal ethical norm of 'help each others', and help the man/woman to reanalyze why he/she wants to end his/her life, etc? Or the inaction to help in some way to the man/woman is an acceptable and reasonable decision?
What would you do?
