So..... Someone's son committed suicide.... And they blame a f*cking game????  Seriously?  I mean sure, it does have disturbing content,  but it has a warning right in front of it!
I mean,  come on!  This game isn't just there to tell you to kill yourself,  it only mentions it! 
Maybe..... The game triggered something already there and he just.... did it.  Believe me,  if he takes his own life,  it's for a reason,  not because he played a game and thought
'HeY,  dYiNg LoOks fun!'. He was 15, he definitely had a reason!  Seriously, you shouldn't have even let him play this if it's that dangerous!  IT HAD A WARNING!!! 
One of my favorite games.... Why? 

Why am I even getting worked up.... I have to look at their side too......
Their son died,  and they're searching for a reason he did it.  They didn't see any signs and now they regret it and out of frustration,  they're blaming a game,  which had a warning!!
....
I'm sorry,  I can't side with them.
