Spookybot's argument is valid. Good is good. There's a story I'm reminded of; a man tells his Rabbi that he has been giving money to charity because he wants G-d to reward him, and he feels his actions are impure. The Rabbi says that the people being helped with his money don't care that he is giving it because he wants something, they care only that they are getting help.
I also see a parallel in this in organizations I've worked with. Organizations need good people, and they need money. You have funding to provide great services to people, but if you can't reach the people who need it, they will never know about your services and thus you have to pay people, and that cuts into your profit.
Spookybot does act in a flippant manner, but that's consistent with their character. They act like Q in Star Trek. Immense power, poor social skills, but deep down, they care.
Roko I think is blinded looking for absolution for the wrongs she thinks she did, but in reality, it was stated she was a good cop. She should remember the people she helped as well.
