People sometimes do things they aren't sure about, and then change their mind when the proof is right in front of them. I don't think this makes them a bad person, or wilful ignorance, maybe naive or optimistic, but you could accept employment with a company who you know had "shady" sponsors in the past hoping they'll do better in the future, then when the evidence mounts against the future actually being better, you decide to leave. Human emotions and reasoning could be internally inconsistent and conflicting, yet everything is as it should be, counter-intuitively.
