Wrong on so many levels.
You're making it personal. If you get an asset in game for whatever reason; you know that this stuff can and often does happen. Get off your high horse and rather than keyboard warrioring; get to work resolving it.
Wrong? You must have lots of friends in real-life. Maybe you never lost a loved one to cancer or another terminal illness? Or maybe you're just a *.
The man is dying, and he chose to spend a few hours a day enjoying a video game he loves in the company of its community and his five years old daughter.
This has nothing to do with video game assets. It's all about giving a dying man a positive experience. The assets mean nothing.
This attack is illegitimate because of its INTENT: the intent to hurt REAL PEOPLE, not video game characters, not video game assets.
You should feel ashamed of being a giant * on the Internet, but I know better and you're probably very proud of cheering the idiots who did this.
