Just out of curiosity, why do you play a game that focuses mainly on corruption where bad things happen to the MC if it's seemingly not your type of game? An extra path that focuses on purity would just slow down development of the main path, why not just play a game that doesn't include corruption? Again not trying to be rude just curious.
I can't speak for him but I can answer from my point of view as i'm kind of the same way. ( I played both corruption and innocent saves)
This is really hard to explain. Since I like to play both ways yet I prefer the non corruption path in games when it's there.
While I dont mind corruption gameplay or anything it simply comes down to enjoyment I think. There is just something about staying Innocent or faithful in an NTR corruption game that I find really fun and enjoyable. While I would never say a dev needs to add that optional path when it's clearly against the idea of the entire game. However when it's there there is just something about going against the main concept that is really fun to me.
A better reason why I like to go against the corruption isn't because I want to keep her pure or anything. I'm probably going to contradict myself a bit here but it's because I don't like the idea of seeing any girls or LI get into harms way by falling into blackmail or anything worst , so to me it's a way to play them and keep them safe as possible when a dev adds a optional pure / innocent path. From the small amount of corruption games ive seen most of the time the corruption is done by the guys being a creep or by force such as blackmail and rarely do they sweet talk the girl or manipulate them. Which is why I kind of prefer to try and keep them safe when possible when it's an optional path and play that path first and the corruption one second.
While at the same time I do enjoy playing the corruption path and let them get into the worst possible scenario's possible it's just not as fun or enjoyable as playing the opposite way way. But it is still fun and enjoyable in it's own way.
Sorry if this came off a bit rambly or doesn't make alot of sense as it's kind of hard for me to explain and put into words.
