That's really awful, people just cannot put themselves in another's shoes at all. If someone did that to their relative or friend, they absolutely would murder them. I lost a friend to suicide, not done publicly, but if only someone had been there to help.
i am of the opinion that if someone has made there mind up, they will do it. if he was going to jump, he would of just carried on walking when he got on the roof. he wavered, he was never going to do it.
