It's possible that both things could be true. He may be a greedy liar while still being very concerned about ASI safety and wanting it to be controlled by humanity collectively (or at least the population of each country, via democratic means). Maybe he is only a greedy liar. I don't know. I'm just stating my personal belief/speculation.
