Why do people hack?

I hack in ALOT of games its usally to make money or just help my friends out in gta, but i have noticed that i like hacking even when i am alone just playing not to fuck with people or anything just to have fun i guess.

When you pay for hacks its a subscribtion a monthly sub or you can buy yearly or life time and the developers keep them updated so the people that buy them dont get banned. Do i pay for hacks? No i get hacks that others have to pay for but i know the dev as a good friend so i get them free.
