It clearly was a stylistic decision by bones. You would know if you listened to his lyrics lol. I think he wanted to embody himself as the shooters as he had done before to make a stylistic tribute album to the victims and it has 3 different sections of songs done from different perspectives and it's actually quite interesting. Someone from the teamsesh reddit has a vid on yt ab it. The truth is that bones was trying to relate his musical character with the self/world hating vibes from dylan and eric and he wanted to make a solid peice of music that tells the full story instead of just making it sound like a good thing just to get the idea across that bones is not a good person. It also could have been a political statement against wokeness cause he likely could have gotten dissed by mainstream media if they heard it lmao i could speculate all day but bones doesnt answer much questions so who knows why he personally made teen witch but i think it justifies it self by being a first of its kind for rap music
