So many innocent hats!
Not much to add, but if one wants to learn about the dark timeline/Double trick that is out-of-control Samson, see the very bottom of this page:

SAMSON
This Samson walks a darker path than the one we know. Having chosen to serve himself and leave the rest of the world to its fate, he turned to the vilest method to overcome his reliance on hosts. Who knows if he is a trick by Double to mock the Parasite, or a relic from a lost timeline recovered by Aeon.
Playstyle Speculation
In this monstrous incarnation, Samson has no physical or emotional restraints and is free to deliver face punches...with his face. Or he can harden his fist into a five-horned ram to bludgeon his opponent. Aside from larger versions of Filia’s attacks, he can incorporate the forms of nature’s most fearsome creations including T. rexes, sharks, bears, mammoths, scorpions, and wombats to unleash a barrage of beastial fury. There will be hair, teeth, spikes, and screaming everywhere.

I think the Samson mistrust is rooted in the inescapable fact that he is the cause of her amnesia. Even if he thinks he is doing it for her own good, he is withholding Filia's painful memories from her. Before SGM origin story mode, we had nothing but speculation, so some thought the worst!
There were non-canon alternate endings too:

In Ending B, Filia wishes for her memories back only for Samson to exclaim "Don't! You asked me to...!"
This doesn't align with the current canon (Filia doesn't ask Samson anything as she is unconscious and dying thanks to Vitale and Ottomo) where Samson is forced to improvise to save her life.
