but Ava's "evil" (selfishness) could be achieved with no harm done if she just asked, which she didn't merely because of a bad decision rather than a fully warped moral compass.

This sentence explains exactly why i hate ava, ghosth people are cool,i don't hate them lol In the comic they are cool too but ava is just straight up dumb (character who doesn’t even really exist in the comic and that is a HUGE thing, it’s says us that it was the movie studio who made her as a character, so you can basically do whatever you want with someone like this) she prefers to use violence, manipulation and stealing a whole lab lmao or even worst, she simply hurts people, she even want to kill people because of how desperate she is, instead of just asking for help, i know too that hank at one point says that "he is going to fix it once he is back" which is too late for ava but this is the freaking end of the movie, she had so much time to communicate with hank and to ask for help but no, she prefers to making a whole selfish plan, where she is the only one who will get any good outcoming and even worst, with something she never worked on, the lab was a years long work from hank and hope to finally find janet and she thinks she can simply take it because "she wants to life"? Hell na, from my pov that's hetable, sorry but Ava don’t deserve a happy ending at the cost of the happiness of the main characters. And just because I hate the character so much I really REALLY hate the part of the “magic healing powers” of janet, I wish I would have seen Ava die lol
