"Power corrupts" that's has proven true since ancient times.
I consider myself an avarage guy (pervert)... what would I do if I got the power to manipulate someones mind and change their perception of me... add to that, that I know several smokeing hot women that while flirting have no romantically or erotic feelings to me...
Certainly I wouldn't share my new Powers and act secretly (so any Super Hero scenario is off)... if my Powers are artificial I'd be the target of any secret organisation possible... but would that prevent me from useing my powers all together? Hell No!
So takeing my own approach on such a scenario I'd say the MC just followed his own Agenda realising that his power is as much a curse as a blessing to him... than he meets Mindlos and becomes entangled in his "game".
He suffers and is forced to see the effects of his own actions (fulfilling his own selfish desires) and realises it's to late to change that... but he also learns that these actions provided him with usefull and resourcefull "allies" (by force).
He can't undo his prior manipulation and he needs their help to stay alive and free of Mindlos... yet he can no longer ignore what effect his actions have had on the girls... he needs more power and resources to get ahead of his enemy that already is more powerful, has more resources and slaves... add to that the missing scruple to further use his powers and his god complex...
The Player is no Saint and is painfully aware of that, he realises his limits and is forced to take actions against an over bearing powerful enemy (abduction scenario). His guilt eats away at him hencefor his ammnents when changeing his programming of the girls. He can't stop doing so or his previous victims will be the ones to suffer, so he searches for something good he can do for his future victims... Mindlos has no care for his victims and uses his powers to conceal his himself from prying interest while building his powers to take over the world... or what ever, we don't know enough to talk about his endgame scenario.
While I do agree with your assessment, I don't quite believe the dev is a good enough writer to implement the psychological aspect of your everyday perv getting mind control. Or, even if he is good enough I don't have the confidence that he would do so. I expect a half baked story going onward.
And honestly, I just want some plot device that alleviates my displeasure of the MCs actions going forward. As I said in one of my posts on the last page, I'm not a fan of the MCs change of heart. I'm all for the MC doing what hes doing vs how Mindilos does it, honestly id likely do the same thing in his shoes. But, its the way he gets there that bugs me.
In a real world scenario you brought up, would you just hold you, and your harem up, while thinking "Ill use this one stranger to do everything." Of course you wouldn't that would be stupid. Rather your guilty conscience is effecting you or not. Your will to survive, and save those you care for would be strong enough to want to do something. Rather, I hope you would.
For example, I personally would seek out those who interact with a lot of people. Just manipulate them enough to get information from them. Shit like a university professor, bartender, someone who works for a large company, etc. They wouldn't need to be apart of my harem, doesn't need to be a female. Just an average person doing average things. Create a network of people who may notice something and point me in the right direction.
Yet, the MC wouldn't do something like that now. Previously he may have, but his guilty conscience out weighs his desire to survive, and keep those close to him safe. Prior to the change of heart, the MC would have panicked, but would do anything to remain safe. That's exactly what he did when he broke into that chicks house. He was willing to do what he thought was necessary, even if it was wrong.
By using real life psychological issues to justify why the MC does something or doesn't is a complex story that I'm not confident the dev is capable of, or even willing to do. That's why its easier to speculate random theories than to draw parallels to reality. The idea of random unknown side effects is an easier pill to swallow for a porn game as well. Otherwise the story may fall flat, or transform into some DeLuca Family depth of story. Which personally Id support.
I disagree that power in itself inherently corrupts, it merely reveals what is already there.
This is something along the lines of what I said. The serum boosted his urges. Which has boosted the MCs urges. How he started as a normal pervert going balls deep as much as he can, than seemingly at the drop of a hat (drinking the second serum) wanted to become a good guy.
