Yes one of the best parts of GTA. Seriously I cannot stand all these "goody two shoes", holistic, "gaming should be fun and not violent guys" who want to take away the best part of gaming. Blowing up stuff. The best movies are based on dark humour.
Have you seen "From Dusk Till Dawn" or "Once Upon a Time in Mexico"? Much better movies than High School Musical from Disney. Gaming is similar.
Besides violent movies didn't start with GTA, I think it started with Doom.
