Still with me? Alright, so in "Dark Waters" there's a point where Damian Darhk kidnaps Felicity, Diggle, and Thea in an apparent ploy to gain leverage over Oliver and use him as a puppet in controlling Star City. It turns out, however, that his real plan is to kill them in order to destroy Ollie emotionally and psychologically. Unfortunately and this is the tasteless part, he plans to kill the trio with a gas chamber. A gas chamber.

I checked the Arrow tag on Tumblr as I usually do when I'm watching the show and boy, to say people were upset and downright pissed off at the showrunners for putting Felicity in a gas chamber would be a pretty accurate statement and I honestly can't blame them.
So, will this permanently wreck Arrow? I doubt it. I would be surprised if the show didn't lose fans because of this and there will probably and should be a backlash from the fandom because of this, but I don't see it having a hugely negative impact.
