I feel like LikesBlondes is trying to imply something like a humanity system, but he doesn't really commit to it any time he wants to get to the "fun" parts more quickly. So, bringing the boy's corpse back to his parents and hiding it from Andrew were the nice things to do and you'd gain a humanity point. But after that the quickest way to get this plot line over with is to just have Andrew deal with it off screen.
There are a few plot points that get rushed like that. Like, the MC just needs to meditate once to control the beast, so we can get to collecting hot blood dolls more quickly. Controlling the beast was a major point in Sharon's characterization and her teachings to the MC in EP. 1 and 2, but it quickly became less important, when the MC needed more blood to get his dick hard.
Or the whole thing where Laurie is supposed to be the MC's best and only friend, where they're supposed to work better together than appart and the MC wants to give her live changing money (like 50k), when she can't make it to a gig, because they're such a great team. Then she just gets enthralled really quickly, because dominating sexy childhood friends is more fun. Her enthrallment felt pretty rushed, considering it fucked over their established power dynamic.
I think the problem is that the dev likes the idea of seperate good and evil playthroughs, but there just aren't enough choices and variables for it. In the end it seems like we're collecting or losing humanity points that don't actually have an impact, but rather come across as plot holes, because things matter at one point, but then they don't, so the MCs morality is all over the place.
