Why Arishem Didn't Capture All Remaining Eternals At The End Of The Movie?

Eternals features the team and their inventor, the Celestial Arishem, who eventually takes 3 of the Eternals with him and allows Druig, Thena, and Makkari to go - but why? Phase 4 of the MCU does things in a different way by encompassing films and Tv series, and in addition to fulfilling the adventures of already existing characters, it introduces new characters who have been redefining the well-known Marvel blueprint. Eternals, one of the most recent MCU films to join this universe, concluded on a significant cliffhanger.
Sersi remained on Earth with Phastos, who had already created a family, and Kingo, who refused to leave his popular movie career after she stopped the emergence of another Celestial named Tiamut using her transmutation powers, through which she turned the Celestial into stone, while Sprite was turned into a human by Sersi and the remaining energy from the Uni-Mind. Later, Thena, Druig, and Makkari departed Earth on the properly repaired Domo in quest of other Eternals and to reveal the truth about their origins and true mission.
Nevertheless, at the end of Eternals, Arishem showed up outside Earth's orbit and took Sersi, Phastos, and Kingo with him to assess their experiences and make a decision if humans deserved to be spared, but he let the ones in the Domo flee, and the possible explanation for this could be that they didn't remain on Earth.
After spending years among mankind and seeing them flourish, every member of the Eternals got connected to them, although some formed a deeper link than others. Sersi was the most empathic of the bunch, with a deep connection to humanity; Phastos is the only one that had a genuine family and didn't want to compromise his family's safety; & Kingo had a long and successful career as a Bollywood celebrity. Now, because Arishem aims to evaluate their memories of humans on Earth and make a final judgment based on that, it seems logical that he took them and not the others, since they are unlikely to have a real attachment to mankind.
However, it still appears strange that Arishem only took 3 Eternals on Earth and allowed the rest to escape, especially because the ones in the Domo are on a journey to spread the information about their history and mission, which might be damaging to Arishem and the rest of the Celestials. Eternals isn't without plot holes and contradictions, and although Arishem seizing Sersi, Phastos, and Kingo makes perfect sense in terms of narrative and setting up a sequel, Thena, Druig, and Makkari escaping from their apparently omnipresent creator feel weird.
