There really is, so I think it must have been deliberate. But it's just handled SO poorly. I can't tell if it's because of the time in which they were made or because nobody told George what sucked and what didn't.
Probably the latter, considering ALL THE OTHER ISSUES. /o\

That's one of the reasons I liked TLJ so much, it tackles the same problem but with so much more nuance and insight instead of going "EMOTIONS ARE BAD! SUPPRESS YOUR EMOTIONS! OH SHIT, HE'S MURDERING EVERYONE, HOW DID THAT HAPPEN?"
LOL. I shall alway summarise Anakin's fall like that from now on. :D
