I searched the fora, and the walkthrough, but no definite answers.
I'm looking for a list of some sort of the conversation options you have to pick to gain Humanity. I remember from previous playthroughs that it can get tricky, i.e. not every option in which you express "Kindness, Goodness, Humanity" (Don't think too much of those as synonyms...) do not always give you a gain.
The FAQS at GameFAQs didn't bother either with explaining this.
Thanks in advance!
There are lots of part when you can get a boost on humanity.
Now I remember just two: The part where you need to go kill the Rabbi's golem that went crazy (Just say Ecaterina that waiting too much will make him kill lots of people) and when you need to go to kill the priest Luther Black, you can say him you won't refuse your claim of humanity and that you won't kill him.
Edit: Another time is when you go to the prince after you founded the Giovanni's hand into Josef Tunnel. When you meet the prince, say him that he is not giving too much attention to the victims to gain some more humanity.
