Yes, they enabled alot of people to go meddling across timelines and created and handed power to people likely not intelligent or wise enough to use it. They actually have the possibility to go back and stop themselves from enabling all the mayhem and destruction, but choose to amuse themselves instead.

So since Elizabeth goes back to kill people that havent done anything yet, why not the same for the Luteces (or just Rosalind who set this whole mess into motion). Seems stupid to chop at the tail when you could cut the head off the snake.
