The twins only care about making things right/getting back at Comstock a little bit, they're more interested in observing how the situation plays out every time as they make small changes, which is why they tally what option Booker chooses and all that, it's all an experiment to them and they're pretty amoral people so they don't really care if they're ruining Booker's life (he was a deadbeat alcoholic so there wasn't much to ruin anyway). Elizabeth is a timelord because her pinky got cut off by the portal when they kidnapped her as a baby so technically she exists on two realities simultaneously, this causes time and space to glitch out around her and with time she learns to control these glitches to open portals to wherever she wants. The zeppelins were super technologically advanced since the entire point of the floating city and Elizabeth is that they have far future technology thanks to her being able to open portals to the future and steal technology from it. Nearly every other point is because it looks cool, because the gameplay demands it, or because of budget constraints, might as well also complain about people being murdered in JRPGs while you have 99 phoenix downs in your pocket.
