Why do people get offended when...?

...when someone says they want to commit suicide? Maybe they have a viable reason for wanting to die, I mean some people actually do have really difficult lifes and maybe they feel it's the only way out, not that I support suicide or anything but why do people have to get so offended, there is this girl in my school whose parents took her out of out school after everyone heard of her suicide attempt, after they heard they were all ragging on her!, she's already in a delicate position why do they have to push her even more?
