Yep. I mean, the problem with crap like this, is the fact that it doesnt TAKE a scientist to work this stuff out.
We watch a guy dressed in a full black metal suit coldly kill people for trivial reasons in multiple ways, and also longs to take over the entire galaxy.
Anyone who NEEDS a scientist, psychologist... hell, ...even your MUM, to tell you that Vader has mental problems seriously needs to go and re-evaluate their intelligence level.
As for the french psychologists...well as with all this Pop science - its done purely just to generate interest in their uni/college/institute in order to raise their profile in order to hopefully gain donations. If they were properly funded by their governments, they might actually be doing worthwhile science instead of trying to pander to the masses with pointless advertising dressed in science like this.
