Honestly, seen corruption take the form OP mentioned, and also other forms. It varies a lot. My issue is less the corruption, than that the dude behind the plan is just too detestable to root for, even in a kinky way. Driving someone to suicide is just a bridge too far, and just makes me want any ending where he loses, whether it's a Pure Aura, or an Alicia rebellion at some point. (Golden ending for me would be for Rose to loosen up a little, Aura to lose some of her arrogance and excessive self-sacrifice, and Alicia to mellow out on her maliciousness and all of them to form a polycule, but that's... not likely, is all I can say.)
