This is a good point, though I only agree about the opinion that we shouldn't shelter other people from the things life is capable to do. If the solution people give me in order to "fix me" is "live with your trauma and learn to cope with it" then I would like to politely answer in kind about my suicide.
I have seen and experienced things that are so much worse than a simple "someone close took his own life peacefully" that I am convinced there's a high probability people will recover.
That they would learn things from it though? Nah, I don't have that kind of faith in people lmao. My family will most likely never reflect on my upbringing and will blame whatever suits them, my laziness, the fact that I didn't make the right choices, didn't do this, that, didn't follow religion to the letter, etc; it's a defense mechanism after all. My friends will probably think this is another one of my episodes like the previous ones that landed me in the psych ward and in jail.
In any case, they WILL recover, I'd bet my life on it. Oh wait. :)
