Re: Anne Hathaway as Selina Kyle/Catwoman XXXIV
The LoS is part of the reason of the formation of Batman, and thus can be seen as the undoing of him as well.
IMO - The League seems to have been using Gotham as it's testing grounds for destruction. However it continued to survive despite everything they threw at it. So they (what was left of the league) decided that they should take matters into their own hands. Also the league at this point were the 3rd tier of the league. The lowest rung with something to prove since they couldn't run with Rah's. So my guess would be that they aren't exactly as disciplined.
