If you have ever told someone to go kill themselves, said you hope they get cancer, told them you hope their parents die, or anything of that matter, I recommend that you go see a psychiatrist. THAT IS NOT NORMAL. You have lost touch with a core value that reminds you that the person on the other side of that screen is a human being.
Even if you find yourself being toxic on a regular basis, there is nothing wrong with seeing a psychiatrist. I have seen a shrink in the past and I loved it. It helped me be the person I am today. Even though society has deemed it embarrassing to see a shrink, it is great to have someone to talk to.
Please recognize that being courteous to those around you is normal. Not freaking out, not telling them to uninstall, and not shooting a few insults their way is a better way to live life. By simply changing the way you behave, you can change the outcome of someones life.
What if that person you told to go kill them self actually does? That is on you. In my opinion you should be prosecuted by law as if you were in the room with them trying to convince them to commit suicide.
I don't know why i felt the need to write this post. If you are someone who is considering ending their life, please seek help. I will help you if I need to.
The worth of every soul is great, no matter who they are.
TL;DR Stop being a jerk and stand up for those around you. No one deserves to be treated like people are treated in League.
