Yeah I mentioned it in Philly's Discord maybe a couple of weeks ago, and pretty much got the same feedback that you just said; that she's too popular, fan backlash, etc. but it really hasn't changed my mind about her. It's not the same guilt or situation that Sonja feels about shooting the girl, but for some reason, it seems like she'll do anything to protect her.
Vic is an augment, just like Henry was, and it just nags at me thinking she'll battle the Red Moon at some point. It's possible, not probable, but it's there.
About whacking her out, yeah it is a very big character to knock off. I mean, in Depraved Awakening, Stella's death was a major part of the story, and you had to figure out who killed her no matter what route you were on. She wasn't an LI per say, and certainly not a major character like Vic is, but she definitely had some sexual run-ins with Jake, one of them being the threesome with Carli and Jake.
It would be a ballsy thing to do for Philly, that's for sure, but I've played more than my share of these games to know to expect anything. That would certainly be an "expect anything" moment.
