I think Bonbi is shaken by outbursts of anger at society. I also had outbursts of anger at society before. In part, I extinguished them by playing to Brutal Doom

In these games, there are no normal people among the opponents, only monsters and a crime scum

I will not recommend the same to anyone. It was only for me that they reduced their anger and hatred towards society. Someone from playing these computer games can, on the contrary, become even more evil and cruel
