Its murder.

I understand your points and there is no doubt they are intelligent (so are apes and border collies) and have protected people. But note how we project those qualities that we like on the whole and blindly see anomalous behavior as the norm.

We also know the 3rd density is about having the opportunity to make choices, experience catalyst, self-reflection, archetypal patterning, tool-making, culture, creativity, planning for the future, etc. In the wild, dolphins are parasite-ridden creatures with a 20-year lifespan. Killer whales (also Cetaceans) have been documented hunting and eating dolphins. Dolphins will attack and kill other Cetaceans: porpoises (which don't compete for same food supply). Male dolphins normally bite and scar each other in competition for females. Dolphins will kill their own pups.

there are still tribes cannibalizing in africa and south america.

a goodly amount of world population would not qualify higher than various octopi or many cetaceans even with the iq scales we are deeming intelligent in our societal science.

dolphin/cetacean intelligence is not comparable to colis. you cant even reasonably communicate with apes to the extent of them being able to cooperatively participate in complex interactions. lack of communication is not an indicator of lack of intelligence, however, existence of communication is an indicator of intelligence. cetaceans can mount shows and interact/communicate intelligently with their caretakers.

if you had to live in the wild, you would be parasite ridden too. the current state of world civilization has only been possible due to excessive amounts of information transferred (undeservedly and before its time) to this planet through waves of wanderers incarnating. had there been no need for such a wanderer operation, this world would also follow similar lines with other 3d worlds.

even still, just 150 years ago people were also living pest ridden lives. (even though the wanderer waves had started earlier).

as a sidenote, i have expressed that extinction of killer whales would be fit and proper, along with many other species on this planet.
