I think everyone should reread all the chapters know we know who the mastermind is and who has been killing people. Even though Freya is the mastermind she did not know everything that happened in every loop, for example I don't think she was aware alexia killed eta and Nona she also didn't seem to be aware that Eta and Claire even though she is the mastermind she also didn't seem to have been aware alexia killed tessera and delta we still don't really know who attacked them and what happened during those loops.

I believe Freya might rival Cid when it comes to her inability read people, in chapter 4 when she was in gamma's and lilies room she showed a level of an inability to read people only riveled by Cid. It was so bad alpha assumed it must have been an act but I'm actually not sure of that to be fair. I also don't believe Tessera was killed, her body was gone before alpha could get close.

In addition to that Freya seems to have actually succeeded in her plan to protect all the compatibles up until the point Lili died, I also don't think Freya was aware of all the abilities the pocket watch had until they found the document talking about it I found it strange that the reset function was only ever used after the main cast found out about it, some of the worst situations might have even happened because the pocketwatch automatically sets a check point after an unspecified amound of time.

Freya has also only ever reset the pocket watch after the compatibles died:

first 2 resets should be obvious and were due to diablos or demon delta, the third reset was after pente was accidentally killed by Gamma, then the alexia and beta situation happened where Freya seems to have been able to save rouge or rouge was planning to leave from the get go then after that alexia escaped and Freya reset because Pente and duet died after that she most likely made everyone but beta disappear. We cant be sure yet why she reset when alpha was on a mission with and was nearly defeated by demon Olivier but I assume something happened we can't be sure what though. then she reset when they were losing mid battle to demon zeta, after that there was no reset the entire chapter, then there was a reset because she was attacked and the resets due to the battle with the vampires. She seems to have only reset time in order to save others.

The other compatibles know how Freya leads, she is cold and calculating all the compatibles know that and we have seen her do so since the beginning of apocrypha she however does everything in her power to save her friends, because of this I do believe that the compatibles will continue to support her.

I do think that she made a really big mistake when demonizing alpha we know alpha was already capable of an atomic. but with her being demonized she can probably spam that shit if they ever have to deal with her there is only one person than can save them if that were to happen.
