okay so this is gonna be a long comment so you're allowed to grab a popcorn or some other snacks
if I were him and I have a shotgun,I would shoot them slowly one by one so the next victim could suffer extreme fear
I would 'mental torture' (you can search that up for more information) them and shoot them afterwards
just watching them tremble in fear while begging for their lives would be nice
I'm not a pyscho so don't call the police on me
I would do the same it's sound awesome ?
