As brilliant as Elliot is, he is also idealistic and hyper-focused, and I think he loses sight of the forest for the trees. The show started with him being on a hero crusade to take down individuals for their wrongdoing. The first hack we see is the coffee-shop guy with a child-porn site. He then tried to rescue his therapist from the married guy and was surprised that she was upset. He later took down the prison warden for his dark-web dealings. It's been Elliot's theme. I can almost believe that he only wanted to relieve people's debt and hurt E-Corp., without realizing how it could affect the greater economy. There might have been a comment somewhere to that effect - that he didn't realize how far things would go. Then there's Mr. Robot's involvement, without Elliot's knowledge, so how much is "Elliot's" fault? He's the hero while Mr. Robot is the anarchist - different degrees of the same tendency.
Elliot's zeal and myopic view were on display again in this opener when he rushed to the fake-guy's apartment, so eager to take down whiterose (apparently it's not capitalized, and it's all one word - I never knew that), that he didn't see the trap. However, the fact that he was able to undo the hack shows that the Mr. Robot part of him did have a recovery plan of sorts. While there was no plan for handling the economy post-debt-erasure, Mr. Robot was at least aware that there could be bigger consequences than intended and kept a door open to restore everything.
As for Angela, she pushed some very dangerous people, and there were consequences. She built herself up so much with her affirmations that it made her kind of delusional (including thinking that the way she manipulated Price was due to her newfound "power"). whiterose could have killed her straight away, and might have left her to her madness, but Angela wouldn't stop pushing. Not saying she was wrong in how she felt; she just really didn't know what/who she was up against. I fear that madness would have been her outcome anyway, had she lived, and assuming the whole thing isn't reset with time travel or into some sort of repeating loop. (I'm hoping Sam Esmail has a worthy surprise in store - fingers crossed.)
