I completely agree with you - there’s absolutely no reason that losing in a video game should be reason to tell someone else to commit suicide. I do not know whether to fault the individual, parents, schools, the internet, or what - to be honest it’s likely some combination of all of these - but it’s absolutely reprehensible behavior.
I am encouraged that more jurisdictions are arresting and convicting people for encouraging suicide through the internet/texting/messaging/etc - maybe the news regarding these cases will be what is necessary to convince people to stop doing this. People claim “nobody commits suicide based on things they’re told online” - but that’s simply not true. We will never know the full impact of suicides due to online bullying because many suicides do not leave notes and parents/relatives may not even know about the person’s online activities, or not know the extent of the bullying/encouragement. If even one life is lost because of someone behind a keyboard trying to be “edgy” and encourage someone else to commit suicide, it’s too many lives lost.
While there’s an argument for human tendency to get frustrated and be angry at people, leading to flaming behaviors, there is absolutely no human tendency to tell others to end their own lives simply because you are frustrated with them.
