why do people hack?

People hack because they're dicks. They LOVE to annoy everyone on the server/match and get those spicy angry reactions. Their definition of "fun" is different than ours.

Because for some people, they are happy to being the "best" and when everyone say "Whoooaaaa you are too skilled" they got an erec... Ahah xD

Juste because they love being adulated ^^

they hacked someone to steal their data. money. e.t.c a hacked encrypted my full harddisk with ransome where rs256 and send a note to me to give him a half bitcoin then he decrypt my data.. that is why i hate hacker..

Well some people just simply do it for satisfaction or just annoying others. Depends on the game really, there is a mobile game called "Last Day On Earth" and it's for iOS and Android devices and iOS users use hacks like free upgrades, duplicating items, free crafting and etc because on iOS you can save your progress on your GameCenter account, doesn't matter that the game files are modded. Android users can't.
So yeah that's one reason to hack I guess.

It obviously gives them a kick in terms of having more fun than others

I can be a pretty fun thing to do as long as you're not a douche,

because he want to add more fun to games and be happy

People who cant stand to lose but are unwilling to put the work in to win honestly are going to have a bad time outside of moms basement. Fortunately for a lot of them they never will leave, just project their own insecurities screaming online about how everyone is trash at their game.

They're feeling happy with hack just ignore them. They think they're good for real (with hack)

well not all types of hacking is bad. There are white hackers but people do it for various purposes, for fun, for annoying, for items. and etc.
