I don't think we should jump to this conclusion so easily. We literally have no first hand experience with Ramah of any kind and only limited contact with Titan. However even without that experience we know that they both ignore the free will of sentient creatures by enslaving their minds. Even if that was the worst thing they've ever done, that still makes them pretty evil. But it hasn't been the worst, Ramah's followers in particular have been continuing this by trying to temper the Slyphs of Little Solace.
