do u think alice does the right thing by leaving in breaking dawn ?

yeah i think she does even though it would be whole lot easier if she told everyone what she planned... after all she did it so she can save nessie and her family.. she wasn't running away, but trying to help.. and in case she failed to find nahuel she made sure that bella gets nessie on the save place.. so i think she did (after you think about it you get to that conclusion even if you at first don't like or approve what she done, i mean left )

ofcourse, if she didnt leave then they wudnt of found that other half vamp half human guy. And renesmee would of got killed =(
