Check your timing. He began making unclassified memos before the discussion of Flynn. It was immediately following the dinner with the loyalty conversation. At that point, there didn't appear to be any indication of intent to meddle. Nothing in Flynn's testimony suggested such. One might interpret it from the loyalty discussion... but I think it's only such a clear association because we already know what followed (Flynn). At the point in time that Comey began making his detailed memos unclassified, he did not have any clear indication from Trump that such things might be asked.
At best, it was a suspicion, a lack of trust of Trump. But at that point he did not know anything about Trump's potential meddling in investigations. His decision to make unclassified memos occurred prior to any event in which Trump's actions can be reasonably viewed as an intent to meddle in investigations.
Reference:
Jan 6 - Comey brief's Trump about "salacious" material (pee tapes). Comey immediately creates a classified memo of the events, based on his feeling about the kind of person Trump is. (1)
Jan 27 - Comey is invited to dinner with Trump, Trump inquires about Comey's desire to retain his position, indicates that he needs and expects loyalty. Comey sidesteps that implied request. Comey subsequently documents the interaction in an
unclassified memo. All subsequent memos are unlcassified.
Feb 14 - Oval office meeting, Trump excuses averyone except Comey and expresses his desire that Comey drop the investigation into Flynn becuase he's a good guy. Comey does not commit, but gives the appearance of agreement by repeating that Flynn is a good guy. Comey shares the events with the FBI leadership team, but not with the Attorney General, and not with anyone in the broader Department of Justice, on his belief that it could influence the investigation. (2)
Mar 30 - Trump calls Comey regarding the "cloud" created by the Russia investigation. Trump expresses agreement that he wants the investigation done properly, and wants it to be found if any of his "satellites" had acted inappropriately. Trump asks Comey to make it known publicly that Trump is not personally under investigation. Comey documents the session and additionally reports it to Acting Deputy Attorney requesting guidance.
Apr 11 - Trump calls Comey to find out what Comey had done toward releasing the information that Trump wasn't under investigation. Trump said he would reach out to ADAG about it, Comey concurs that's the right way to handle it (3).
Trump isn't under investigation, and has never been. Are you suggesting that in order to conclude he has not colluded with Russia, you require the FBI to launch an investigation, regardless of the fact that to date they have apparently felt that such investigation was not merited?
Are you holding Trump personally accountable for the actions of others, and condemning them for their behavior?
I didn't ask you for ideas about what would NOT convince you that he hadn't colluded with Russia, nor for speculation about things that haven't happened. I'm not sure why you bring up potential future maybes here.
Am I to interpret this to mean that unless firm evidence shows up to "prove" that Trump didn't do a thing... you're going to stick with your opinion on the basis of hearsay? Do you hold that same view in other cases where it's one person's word against another's with no solid evidence, or do you apply different standards to Trump?

Notes:
(1) This is from Comey's live testimony before Congress, not his prepared testimony. He repeated his assertion that the "nature of the person" and his lack of trust of Trump was a major reason for making the memos.
(2)
Question: Does Comey feel that other people within the investigation are not as stalwart as he, and would be influenced to cease the investigation if they knew that's what the president wanted?
(3) I interpret Trump's comment as an implied threat to Comey, essentially "If you're not going to help me, then I'll just go to your boss"
