About Caesar's promiscuity (and Gurdjieff's), I think this is part of "judging morality", so to speak, that G explained. Morality is not useful, conscience is (and conscience is universal, while "morality" is different from place to place and time to time - and has often led to great hatred and destructiveness). Also G said that abstinence can be useful in the work, but it depends on type (of man) and if it is done consciously and in EVERY center, otherwise it is the worst abuse of the sexual center, if one abstains from physical sex/sexual energy release while having repressed sex energy running other centers. Plus, G said about the types that according to type, some have to abstain from releasing sexual energy, some, on the contrary have to expend a great deal of sexual energy, and for others it didn't make a difference. And for the first two types, it only mattered until transmutation/fusing had begun.
Also, killing is even more "problematic" than being sexually promiscuous - but again the question is in what situation and for what AIM was the killing done. I think doing things with a greater AIM in mind makes all the difference. NOT having mindless sex for personal pleasure only, or killing in an indiscriminate manner or in a fit of anger or to secure personal gain, etc., but appropriate to the situation using the Law of Three. And neither G nor Caesar were perfect, nor needed to be, they were human. The bottom line seems to be that if they made mistakes that hurt others, their conscience would function, and they would learn from it and make amends. Isn't that all anyone can really do - and that's a tall order already for most.
