My problem with Jake is that because of his low self-esteem, He a gullible idiot. One "appearance' of the MC has him believe we're not trustworthy, yet believes everything Ella says. He even goes after normal, innocent people just because Ella says it will make him grow more powerful, then later does so because she MIGHT help him fix his mistake with Mia.
Danika meanwhile, only targets enemies, including us. She starts as an emeny only because we're helping a rival gang. IF you decide to spare her, she even shows some interest in us.
Alexis, meanwhile, is part of the H.E.R.O. group which i don't' trust, though they do have some good people. ( clark and they guy that warned us to GTFO when we infiltrated)
Right now, Jake and Ella are both on my would like to kill list, because i don't trust them at all. Tiffany is another, while hot, I wouldn't mind killing if I could with no repercussions. Knowing her though, she would have some failsafe that would expose us. Alexis and to an extent H.E.R.O., is on my need to learn more before passing judgement.
