You shouldn't necessarily change your negative opinion of someone, just because they're right about something. To invoke Godwin's law: Adolf Hitler was a staunch opponent of smoking, in a time when many Allied cultures thought smoking was great, but that doesn't mean you're wrong about him.
Suppose it's 1940. You know that Hitler ordered Aktion T4, and conclude that Hitler wants to kill people. Then, you learn that he opposes smoking because he doesn't like it killing people. You shouldn't start doubting that he's the sort of guy to sign mass death warrants: you've learned some information about his internal thought processes, but it's not very useful information if you want to predict his future actions.
"Orthogonal" is subjective. All things are interrelated. That does not mean that our descriptions should be highly-sensitive to noise. Update your internal model of his behaviour, by all means, but if you have predictions that don't require that internal model, consider whether or not this evidence should actually affect those predictions.
