Why do people hack?

I presume that the form of "hacking" you speak of is people hacking in games, CSGO for example.
Now I do not consider this real "hacking" as you are not doing any of the work yourself, rather it is being done for you passively.
I can't deny I have done the form of hacking you speak of many times and probably will continue to in the future.
I believe the reason why people do it is because it can be enjoyable to go from always losing or being beaten to being able to reign
supreme over your opponents and be able to almost always beat them in any confrontation imaginable, It just gives you a sense of dominance.
