Cinder did have a foil. It was Pyrrha. Think about it: one person born without power, who desperately tries to gain it; and another person born with enormous power, who works tirelessly to mute it.

The other problem is a technical one. Cinder doesn't make sense as Ruby's nemesis because Ruby can kill Cinder at any moment with (literally) the raise of an eyebrow. That's a huge problem. Villains are supposed to have an edge on the hero, not the other way around. Lex Luthor is the perfect villain for Superman, because he possesses the one thing that can kill Superman: kryptonite.

With Cinder, it's the opposite: Ruby posseses Cinder's kryptonite; and that just doesn't work from a narrative perspective because it takes all the suspense out of the equation. A fight between Cinder and Ruby would be boring, because we all know damn well how it ends. That's why Cinder should have died long ago.
