why do people hack?

Really depending on the person. Some cheat cause they are bad at the game, some are trolls trying to make people mad, or some just do it when they are bored of the base game. Join a Hack vs Hack server and ask them why they cheat and see how their response is. Their is a community built up around cheating and everyone knows each other in a nice community. Not all cheaters are bad some only cheat when they see a cheater on the other team. Like i said depending on the cheater and who they are and how they think.
