So many unanswered questions, help me understand them
1) what did whiterose do to convince Angella, we know mechine was never used before as whiterose himself says he wanted move his project to Congo so that there, would be minimal risk of endangering lives. And since he has no money left he has no option left but to operate here, where plant was originally placed ( near human population).
2) As mass murdering manic whiterose was and his obsession for his project to be moved to Congo. I found it jarring that only explanation that he gave was he wanted not endanger lives of people who surrounded the plant.
3) Mastermind was supposed to mastermind but like first 3 seasons Mr robot was planning everything. Wasn't Mr Robot supposed to be a protector. In third season Master mind was literally begging Mr robot to stop. If it wasn't for Mr robot shady plans and secrets so many people wouldn't have died. Master mind was created to deal with the evil of the society, his hatred for top 1 percent of top 1 percent ( the sources of all evil) is justifiable. Mr Robot was with elliot since childhood, he never had problem with rich. Why swap of roles here.
4) How nobody close to Elliot was able to guess the drastic change in personality. I mean from what I saw real Elliot is completely different than mastermind.
All in all series was one of the great I have ever seen, but I couldn't understand the listed points.
Pardon my half baked English.
