Curse Pokemon leech 50% damage dealt to heal themselves, so they can get insane heals if they use the right powerful move on a pokemon (Head Smash on an regular Charizard at LV 127 would 1HKO it dealing 600+ damage, restoring 300+ HP  for example) So yeah, It's really just due to the fact they can get insane heals which can outweigh the 50% damage resist.
