As regards the idea that aliens who are more advanced than us should be more loving, caring or whatever, I think the terms "service to self" and "service to others" are important to understand. Bill and Kerry use these terms quite often and they come from the channelled information from Ra -

I think this information is very useful because it not only explains how more advanced beings could still wish to harm us but it also gives a lot of info on the various spiritual dimensions and Bill and Kerry will often refer to it so it's probably worth having a look at it.
