Why did Elizabeth need to do all this?


Seems like a clear overreach.
Why did Elizabeth need all these games to take revenge on this Comstock?
We saw her kill Songbird with a snap of the fingers.

Also, was waiting for a Big Daddy to appear really the smartest choice?
As we saw in Episode 2, it was NOT.
If she sees so many things, future, present, past, surely she would have found a better way to solve this situation?
