As I've said, Ras's aims of annihilating nine-tenths of the human population seem to be a little more extreme compared to the ELF.
And I think frankly having the villain being opposed to moral decay and decadence made him more interesting; environmental terrorism is usually a non-starter dramatically (I'm not a fan of Poison Ivy, by and large).

Just how did Rachel serve any purpose in "Batman Begins" besides giving background information on plot developments and characters and being a damsel in distress?
My point was that I'd concede Rachel in that film was more useful then her predecessors... which really isn't saying much. At all.
