I don’t know where I read it but IIRC religion is being used as a simple answer to very difficult and possibly uncomfortable questions: why are we here and what is our purpose?
It is fairly easy to believe that something, a god, created us instead of that the existence of humanity was just a fluke, a stroke of luck enabling us to evolve were we are now because it is just easier to grasp even if it is proven. That we evolved from simple beings into more complex organisms instead of just “being created”. Evolution creates so many quite difficult questions that it is easier to understand and believe that someone just wanted us to exist.
When someone is believing in a religion they also always have some form of " it won’t be over" scenario like when you die, there is nothing truly “the end”. You just won’t vanish and this can be terrifying for many because the following question could be, what sense does it make to live at all when our existence is just so insignificant in comparison to everything else?
So, in short, it is an easy too to make sense of things that almost everyone can understand it.
Unfortunately, things like this can and will be abused.
Short answer: Because their motivation is to win!
I read something about this in the Book “Introduction to Game Design, Prototyping, and Development: From Concept to Playable Game With Unity and C#” by Jeremy Gibson a while ago, maybe that can explain this a bit.
Basically, every Player has some Intention or the “Player Intent” which is described by the Personality Types of Richard Bartle. For example, you have:
And then you have two others that you will be encountering:
So, the motivation to “cheat” could either be that this player doesn’t really care about the game, is able to get away with cheating and just wants to beat the game. According to Jeremy Gibson, a cheater might not cheat if they can win legitimately but I would argue that cheaters are usually not great players in the first place so the bar would be pretty low for them to “win legitimately”.
As for the spoilsport, this is extremely hard to work against or prevent because the motivation isn’t about the game anymore but other players, to make their experience miserable so that the spoilsport can gain satisfaction from it. Hence also the use of “don’t feed the trolls”.
With that being said, when you ask why someone would cheat, the question would rather be “What is their motivation” and the answer to that is “to win the game, at all costs”. And, most of the time, they will get away with this because they apparently cannot be caught as quickly as they can still continue doing it, if there is any action against them at all.
