Look at the bigger picture, most people just look at a particular scene n jump to conclusions... they're trying to show you that most dealers they have to eliminate people for them to survive ( as a person at home, do you want that kind of life or do you wanna associate yourself with that kind of a person?..what are the implications of doing that?) but that's not the whole picture the whole picture will be what's going to happen to Brutus and his family at the end...I'm sure they might all get killed or end up in jail then that's the lesson the Queen wants people to learn...that breaking the law doesn't pay n you may try but you won't get away with your actions forever.
