Before I answer, I need to define some terms.
Corruption - the action of making someone or something morally depraved or the state of being so.
Conditioning - the process of training or accustoming a person or animal to behave in a certain way or to accept certain circumstances.
Violence - Any action taken by an individual or group intended to cause harm whether physical, sexual, psychological, or through deprivation/neglect.
Morality - principles concerning the distinction between right and wrong or good and bad behavior, and the extent to which an action is right or wrong.
Now, I'm a really sex positive individual. I truly believe that within the bonds of enthusiastic consent there is nothing wrong with anything sexual. Therefore, I myself am incapable of being "corrupted" sexually, because my morality would say that it is limiting sex that is immoral. However, I also recognize that my beliefs are not the beliefs of society on the whole, nor are they the beliefs of every individual. As a result, there's a certain joy, to me, in disillusioning someone of their deeply held beliefs. As somewhat of a sadist, I revel in themes of humiliation, exhibition, and corruption. Taking a girl who views their body as a temple to be cherished and saved for godly acts and having her expose it, having her give into and beg for her desires to be sated, watching the sense of shame they feel from these acts, excites me to no end. However, as I mentioned at the top, consent is key.
Conditioning and Corruption are not mutually exclusive, but they aren't the same thing either. You could create a Venn diagram with them and show scenarios in which conditioning and Corruption do overlap, a pure girl consenting to an S&M relationship, for instance, is literally going to be trained to be more of a depraved slut, but, the fact that she chose this means that she is entering a state of corruption. However, if that same girl is only consenting because you threatened to kill her, her body may be doing the things, but her mind and her heart remain hers, and if she ever escapes your violence, it will be her heart and mind that win over, not your training. This is where that definition of morality comes in handy. To what extent is an action right or wrong? If we accept, as the law does, that things done under duress are not the same as those undertaken willingly, then someone being blackmailed or coerced into sex is not making a moral decision, but a survival one. Again, there is some overlap here, the coercion could be a bribe of some type. A better job for a little sex, but no fear of losing your current one? That's a choice to compromise your morals for increased standing. That's corruption.
So, my stance is thus, I like corruption, even in cases where it overlaps with conditioning, but I do not like conditioning. Retard in lechertown games, or games where the love interests are retards in some lecher's harem don't work for me. D, in Dating my Daughter is not being corrupted, she's being conditioned. Mom in Big Brother isn't being corrupted, she's being conditioned. And this is the case with most games with a corruption tag. Authors don't understand the nuance of these two things and thus keep falling to the easier conditioning tropes rather than the more complex and psychological corruption ones.
I wonder sometimes if other people's perceptions of corruption aren't similarly tainted by this lack of nuance. Do people like OP not understand the appeal of corruption because they keep coming across its non consenting cousin, conditioning? Do they try to hold nuanced beliefs liking some corruption but not others? I've found many people hate female protagonist games because they've played a few of the retard in lechertown variety and have this view that all female protag games are just rape simulators. And honestly, it's hard to tell them they're wrong because so many really are incapable of nuance, they do give the player no agency. However, add in that agency, and you nail my kink. I love depravity, I love when a girl compromises what she has been taught to be right and moral in order to indulge in carnal pleasure. And so I love corruption. It's just too bad there aren't more game that do it well, male or female MC.
P.S. - Mind Control/Alteration through whether in fantasy or sci fi contexts is not corruption. If the girl's morality is changed, not by choice, but by force, that force being in the form of powers or pills or potions, they aren't really corrupting anything, because their morality accepts it. Nothing wrong with the power fantasy involved here, but too many games don't get this, hell, one such game is even titled "Corruption".
