genuinly of the opinion that beeing good should be just hardmode.
beeing evil should be the easier option.
beeing truly good is hard. it requires to be altruistic and not to pursue what helps only yourself
I think that is really how the game is going to be naturally; choosing any other option besides the tadpole is going to be a harder DC check. Basically, take the easy route and chance becoming a mind-flayer quicker or take the hard-route and delay the ceremorphosis a bit longer. At least that's how I see it until they give any more info on that.
