There are no stupid questions.
Only stupid answers.
As for your question.
Corruptions is the act of changing something into something else.
In terms of porngames it convers everything from mind break to sluttification.
They key element of corruption games is that they change the npc over time.
To use your examples:
Cheating is all about sleeping with someone else there
property wife.
Useally while trying to avoid being caught(It goes into the ntr territory when the husband is watching but hates it)
Harem is a collection game where you want to get all the girls.
And mind control is complicated.
It comes in 3 parts:
Lazy: Mind control is a cheat mode to slutification and most of the games with the mind control tag fall under this.
Subconscious manipulation: Making people feel wet whenever they look at you or unable to cum or constantly want to touch there boobs, etc.
This mind control is all about turning someones body against them without taking direct control.
Mindless drones: My personal favorite and the most rare.
You turn there brains off.
They dont feel, think or act unless you tell them or program them to.
It turns them into a robot.
It gives me the feeling of compleet control.
I decide how they feel, act, what they do.
At its core mind control is all about taking control away from the person and giving it to you.
Unless its the lazy version.
As for some good ones.

At its core corruption is about changing people.
EDIT:
Technicly speaking turning a slut into a prude would fall under corruption tho i doubt anyone would admit that.
