>if it's a 180 personality
It isn't. Their personality gets mamonofied, but they are ultimately themselves at the end of the day. Consider it a "freeing from the norms and expectations of human society, etc".
>have to just go "and it had no effect"
It's change. You aren't someone else, but you are different from before. Braver, stronger, more confident, less inhibited, sad, etc. It comes down to the person. Monsterization might not change much for someone who's already happy, aside from turning them into a succ/incubus. I don't think this is a bad thing. Corruption/monsterization is best when the person is unhappy with their life or current situation. Gives you the strength to continue forward, or fixes a part of your body you don't want, etc... The possibilities are endless.
If you don't like it because "and it had no effect" because it doesn't turn people into cartoonishly evil/abusive/whorish versions of themselves i guess you will be left disappointed.
>Abyssal corruption and how it affects men has always been a bit of a sore spot for people.
Either you like it or you don't. You don't need to engage with it if you don't want to. Abyssals don't usually force themselves on people(outside nightgaunts), and the transformation is reversible.

>several of the girls just instantly overcome their life long trauma
I don't think that's a bad thing, but if you want a more sensible explanation, it's just that they finally got the power to overcome those traumas, and decided to finally act upon it, with Druella helping that process by giving them a gentle push.
