Why do people hack?

I think people Hack in games is either they hate the game or they arent that good and want to be good at the game.

I do hate hackers in Competive games and i think valve's anti cheat is so bad. Even top youtubers explained how their friend could hack really obvious and not get banned but they had a ESEA client open and they got banned from ESEA instandly while not even playing on ESEA but just for having hacks. That proofs how good vac actualy is. Also the fact that "PRO" players used hacks in tournaments is just ridiculas
