Why do people hack?

I know when I was a lot younger I did use some ESP wall hacks for 1.6. Mostly I would toggle them on and off every once in a while because they actually helped me to become a better player. After being able to see where other players were I became better at know how people position/play. I was casual and didn't really do that well even with the esp hacks. As you get older you dont really do that stuff as much personally.
