Two questions:
- How good / bad is the translation?
- Is the mind control stuff shown as evil mind control or is it the sort that just stultifies them? As in, are we talking mind control rape or mind control for "lust"?
Translation is decent.
IT's MTL but it's GPT powered MTL, which is still inferior to a proper translation (at least for now) but it's plenty readable and generally doesn't have too many gramatical mistakes.
An occasional pronoun out of place or something but much less severe than classic MTL which would often devolve into gibberish.
As for the mind control ... it's revenge mind control.
So it's Evil mind control but the targets are generally depicted as mostly deserving it.
Objectively it's still bad but whether or not it bothers your sense of morality to the point of ruining the game largely depends on you.
At the very least the MC isn't simply some creepy mind controlling rapist that just attacks innocent people for pleasure. If that's your worry it's not to that degree.
