I always liked the Tok'Ra- the idea of two beings coexisting like that, sharing every memory and feeling, is fascinating and I don't think the show ever really did any of that justice. (More should have come of Sam being left with the knowledge, memories, and feelings of Jolinar. We learn in subsequent encounters with the Tok'Ra how common it is for the symbiote or host to heavily influence the other in terms of personality. Is that something Sam struggled with? Not to mention the way they just ignored her having naqadah in her blood.)
But goddamn is Delek an asshole. He's the Council member in Death Knell who tells Jacob/Selmak that the Council has been running ops behind their back. I get when he says that Jacob, rather than Selmak, seems to be the dominant personality and how that clearly chafes. The Tok'Ra are their own people with their own culture and protocols and politics, etc. Trying to have their own society while living inside of other sentient beings can't be easy. The hosts have personalities and cultures that are going to influence things which is unavoidable if the Tok'Ra are going to take hosts ethically. How do you balance the two?
All of the oldest Tok'Ra we saw in the first few seasons relinquished control to their hosts far more often than the Tok'Ra that rose up the ranks in subsequent seasons. In fact, after a certain point in the series Jacob is the only host you ever hear speak. A lot of the younger Tok'Ra who stepped into leadership roles as the older ones died or were killed seemed more...militant. Even relatively sympathetic ones like Malek, who told Jack he had no problem whatsoever with the symbiote queen and her offspring being experimented on because the Goa'uld had done far worse to humans, did not once let his host speak. (Which is notable to me also because I recall Martouf, iirc, explaining they prefer to let the hosts deal with humans because it makes humans more comfortable. By season six or so that consideration is out the window.)
Then there's Delek flat out saying that the Tau'ri haven't had their spirits broken by thousands of years of subjugation by the Goa'uld- and that while that can be an asset is makes them dangerous. So while he probably opposes the killing and enslavement of humans, he does find the effects of enslavement to have a positive benefit for the Tok'Ra in terms of producing proper (meeker) hosts. Maybe the most punchable Tok'Ra from the entire series.
