Zero said that if it wasn't for hacking, games wouldn't be fun. He said cheating is a rush, similar to the one he got when he used to deface websites. “In life, you're always going to have rebels,” he said. “It's like coming up to someone and asking, 'Why do you rape or kill?' But in this case it's cheating.”
Honestly comparing cheating to something like that is pretty bad. I wouldn't even think of comparing cheating in this manner.
I personally never understood cheating in that regard. Single player? Sure (who doesn't love running around with god mode and senselessly destroying stuff for a bit). Multiplayer? Nope. I mean when you begin to destroy the experience for other people just simply trying to enjoy the game that's just bothersome.
In this case people are paying to tip-toe around in games for a big advantage against others. Why? I probably won't ever understand the motivation, but it seems like big business.
