I'm personally very much on the fence regarding bestiality, and depending on its depiction it can be "a little spice to change things up" or "avoid at all costs." The times I played The Manor in the past I would turn bestiality on simply because they almost exclusively involved Vera, who I absolutely can't stand, and it did not bother me as much because I didn't care about Vera anyway.
When and if I ever play the game again (once it actually gets some more new content that I'm actually interested in) I, for one, will be turning bestiality off specifically because it now also involves Martha. Because I actually care about her. So there is that.
