I don't understand your point. Either it's "acceptable" to read things into the photos and videos we have, or it's not--for all parties. Also, I didn't say anything was "equal," so not sure where you're going with that.
Your original point was that people are analyzing his still photo and his news interviews to read into his personality, his actions, etc, yet it is seemingly not ok to do the same when it comes to Shanann's social media stuff, am I correct?
My point is that you are comparing someone's actions on social media, which is notoriously fake (they don't call it Fakebook for nothing) and an MLM business on top of that which also has an image to present, plus this is someone who at that time was not a victim or perpetrator of any crime...
To a man who is on live TV deliberately lying about the lives and whereabouts of his entire family when he's begging the world, the police and the public to help him find them. To bring them back. Telling about her last moments there. All the while knowing they're all dead and he disposed of them in various ways.
I'm sorry, but I don't understand your point about how it's pretty amazing that people see those comparisons as completely different. She was going about her daily business and posting online. She wasn't and had no reason to be deadly serious, completely honest not to mention utterly shattered.
A good analysis of whether they both lie under pressure, or are capable of murder, or can appear emotionless save worry of being caught, or covering up their children's bodies in oil... something serious like that, would be to compare news interviews of both Chris and Shanann after their children went missing. Then you might gauge their reactions more fairly.
But you can't, because she's dead and he killed her. That part is a fact.
