Yes, but not in the way you think; I chose 'He could be a problem' so before he met Mark my MC was unconcerned about the 'ruining her life' thing, and after seeing what a dick Mark is, his thoughts change to 'oh no, I ruined her life by breaking up her relationship with this violent thug'. It's a shame because these two events would be perfect places to give the player input into MC's attitude. But with Gwen the choice is inconsequential, and with Chloe you aren't given a choice at all. What I'd like to see is the MC's thoughts after Gwen's event depend upon what choice you made earlier, and give the player a similar choice in Chloe's scene. I'll admit I'm not sure what the dark choice for Chloe's scene should look like though; even when playing as a dark character I don't know if I would be OK with hurting a little girl.
To be brutally honest, I'd go with Pixie's idea of fucking Gwen and forcing Mark to watch it all.
The reason? Two reasons, really.
1. I have the power to build a world I'd enjoy, therefore, it's my right and duty to use it, my ethics dictate that I'm not allowed to deal damage to someone who never dealt damage to me but, since Gwen was involved with keeping me locked up, fucking her mind was justified and whoever stupid enough to challenge me is begging to be punished without any restraint.
2. He reminded me of Mark Zuckerberg, this is reason enough to make him suffer.
Now, going back to my original idea for a comment (I went off in a weird tangent but hey, who's to stop me?)
There should be more player input and, if not for a karma system, something akin to a clear 'route' (which could be made by just having the dialog being made to suit the prior decision or something like that, I can't make a good explanation about how that would work cuz this is the first time I'm putting this shit into words, so gimme a break.)
His "what have I done" is truly meh. I'd go with: "The world can be mine if I play my cards right, it's time to take careful actions. I'll need to talk to my girls so I know everything about them and their life so that things won't get out of control."
ALSO, I WANNA PROTECC CHLOE'S SIS. (Chaotic Neutral, obviously)
EDIT: About the dark route for Chloe, you could go with NOT having Chloe act like a human with her sister, thus using shatter on the lil' girl.
I mean, if Dark is your route, you can go as fucked up as you want, there's nothing to stop you.
Also, it would be an OPTION, anyone who isn't okay with this could very well not do it.
EDIT 2: A not-so dark approach would be to use the bond Alice and Chloe share to awaken her, making she sees him as an older brother while developing into a brocon or something like that. Hell, you could use that to make him seem like an innocent guy who wouldn't harm a fly (by abusing the fact that his 'girlfriend's' little sister is treated as a real little sister by him or something.
THE LIMIT IS OUR CREATIVITY.
