I destory supplies for money and RP. Especially if i am unable to start VIP work. I mean its not only because i want money but i get text messages from agent 14 or Ron convincing me to destroy them. I know i get hate for doing so but rockstar promotes this act of destruction so much. First a screen pop up prompting us to do so and now contact text messages telling us about rival shipments.
I dont feel bad when i destroy shipments because i feel its part of the game. Its a red object on the map floating around. Great thing we can steal other peoples vehicle cargo and air freights. I never destroy vehicle cargo because i dont get anything out of it and may be a form of greifing.
